“My head is pounding” sounds like a figure of speech until you realize it can be a precise anatomical report. We dig into clinical insights from Dr. Adam Lowenstein, MD, FACS, to explain how some chronic headaches and migraine-like attacks are driven by a literal collision: an artery expanding with every heartbeat and repeatedly striking a nearby sensory nerve.

We map the core mechanics in plain language: sensory nerves thread through crowded real estate, squeezing past muscle, bone openings, and rigid fascia. When that pathway turns into a peripheral trigger site, you can get two very different pain profiles. Static compression from muscle or fascia can feel like a constant tightening band, while vascular compression can feel like a bruise being tapped 100,000 times a day, gradually driving severe hypersensitization through mechanosensitive nociceptors.

Then we get specific about where this happens and how it’s confirmed. We focus on the temporal trigger site, where the zygomaticotemporal nerve can intersect with branches of the superficial temporal artery at the unforgiving temporalis fascia, plus we touch frontal and occipital trigger sites. We also explain the real-world diagnostic workup, from symptom tracking and palpation to targeted diagnostic nerve blocks that temporarily silence a nerve to pinpoint the exact corridor.

Finally, we walk through the surgical logic behind long-term relief: why simply moving an artery may not hold, what “bracketing, dividing, and excising” a vessel actually means, and why collateral circulation makes small external carotid branch changes safe for the scalp. If this redefines how you think about headache causes, subscribe, share this with someone who lives with throbbing pain, and leave a review with your biggest takeaway.

Welcome And Safety Ground Rule

SPEAKER_00

Welcome to today's deep dive. We have a uh a really fascinating mission for this one. We're going to unpack the literal physical meaning behind the phrase, my head is pounding.

SPEAKER_01

Right. Yeah. It's a phrase we all use.

SPEAKER_00

Exactly. And to do this, we're pulling from this stack of incredibly detailed clinical notes and surgical research from Dr. Adam Lowenstein, M D, F-A-C-S. He uh he operates out of the migraine surgery specialty center. And his work essentially takes everything we think we know about tension and headache pain and well, totally flips it upside down.

SPEAKER_01

Aaron Powell It really does. But um before we jump into those clinical notes, we do need to establish a quick ground rule for everyone listening.

SPEAKER_00

Oh, right, of course. Go for it.

SPEAKER_01

The anatomical insights and you know the surgical procedures we're going to explore in this deep dive are strictly for educational purposes. Aaron Powell Right.

SPEAKER_00

We're not giving medical advice here.

SPEAKER_01

Aaron Powell Exactly. Any medical decisions, diagnoses, or treatment plans always need to be made under the direct supervision of a qualified physician.

SPEAKER_00

Aaron Powell So keeping that in mind, let's talk about that phrase.

When “Pounding” Turns Literal

SPEAKER_00

My head is pounding. Right. You have a terrible, stressful day at work, you rub your temples, and you tell your family your head is pounding.

SPEAKER_01

Aaron Powell Yeah, we treat it as this colorful metaphor. It functions as our universal shorthand for misery, you know?

SPEAKER_00

Aaron Ross Powell Totally. It's just a figure of speech we use to say we're overwhelmed and tired.

SPEAKER_01

Right. And when you use that phrase, people instantly understand the specific, unrelenting pressure you're trying to describe, even if they assume you're like just being dramatic about a standard tension headache.

SPEAKER_00

Aaron Powell But going through Dr. Lowenstein's case files completely shatters that assumption. Because for a specific subset of people dealing with severe chronic headaches, it's not a metaphor.

SPEAKER_01

Not at all.

SPEAKER_00

They aren't being poetic. It is a literal mechanical description of an anatomical event happening inside their skull at that exact second.

SPEAKER_01

Yeah. We're looking at a massive paradigm shift here in how we understand chronic pain. When patients with this specific condition say they feel a throbbing sensation, they are actually feeling the physical force of their own arterial blood flow.

SPEAKER_00

Which is just wild to think about.

SPEAKER_01

It is. They're feeling a blood vessel mechanically hammering against a delicate sensory nerve over and over, perfectly synchronized with their heartbeat.

SPEAKER_00

I mean, that sounds like something out of a horror movie. A normal, healthy pulse is supposed to sustain life, not cause debilitating agony. How does an everyday heartbeat turn into a weapon against your own

How Head Nerves Navigate Crowded Tissue

SPEAKER_00

nerves?

SPEAKER_01

Well, to understand the mechanics of that, we have to map out the geography of the nerves in your head.

SPEAKER_00

Okay, lay it out for us.

SPEAKER_01

Sensory nerves don't just like magically appear on the surface of your skin to let you feel the wind on your face.

SPEAKER_00

Yeah.

SPEAKER_01

They originate deep inside the complex tissues of your head and neck.

SPEAKER_00

Right.

SPEAKER_01

From there, they act like biological cables, threading their way outward to supply a sensation to your forehead, your cheeks, your scalp.

SPEAKER_00

And I'm guessing their path to the surface is not exactly a wide open, empty highway.

SPEAKER_01

Oh, far from it. The human head is incredibly crowded real estate.

SPEAKER_00

I can imagine.

SPEAKER_01

Yeah. So to get from deep inside your skull to the surface of your skin, these delicate nerve cables have to navigate some treacherous terrain. They're squeezing past heavy active muscles and poking through tiny rigid holes in the bone. And they're penetrating multiple layers of fascia.

SPEAKER_00

Fascia. That's the stuff wrapping the muscles, yeah.

SPEAKER_01

Right. Fascia is a dense, highly unyielding sheet of connective tissue that wraps around our muscles. Think of it like a very tight, tough biological casing.

SPEAKER_00

Okay, so what happens when one of those pathways gets just a little too crowded?

SPEAKER_01

That creates what surgeons call a peripheral trigger site.

SPEAKER_00

A trigger site.

SPEAKER_01

Yeah, it's essentially an anatomical bottleneck, a specific highly localized point where the corridor is too narrow and the surrounding structures begin to close in on the nerve, compressing it.

SPEAKER_00

Right. And the notes actually detail two very different types of compression here, which I found fascinating. In a standard tension headache, the structure doing the squeezing is usually a muscle or a rigid band of that fascia we just talked about.

SPEAKER_01

Exactly.

SPEAKER_00

And from what I read, that creates a static compression because if you have a tight stressed muscle clamping down on a nerve, it's applying a steady, unyielding force.

SPEAKER_01

Which matches the patient descriptions in Dr. Lowenstein's notes perfectly. They describe this imploding sensation like wearing a heavy

Static Squeeze Versus Pulsing Strike

SPEAKER_01

iron band wrapped tightly around their skull. The pain is constant.

SPEAKER_00

Because the pressure is constant.

SPEAKER_01

Right. The baseline mechanical force of a tight muscle might fluctuate slightly over a few days depending on your stress levels or how you slept, but the physical pressure on the nerve is essentially constant.

SPEAKER_00

Okay, but vascular nerve compression introduces an entirely different mechanism.

SPEAKER_01

It does. The structure crowding the nerve in a vascular trigger site is not a static muscle, it's an artery.

SPEAKER_00

And arteries are incredibly dynamic.

SPEAKER_01

Exactly. Because they're living hoses hooked directly to a pump.

SPEAKER_00

Right, the heart.

SPEAKER_01

Yeah, they don't hold a fixed rigid diameter. Every time your heart muscle contracts, it sends a highly pressurized wave of blood.

SPEAKER_00

The systolic pulse wave.

SPEAKER_01

Right, surging out through your circulatory system.

SPEAKER_00

Yeah.

SPEAKER_01

And as that wave travels through an artery, the walls of the vessel have to physically expand outward to accommodate the sudden volume of blood. Then they relax.

SPEAKER_00

Aaron Powell So if a dynamic artery happens to share a microscopic doorway with a delicate sensory nerve, the nerve isn't getting a steady static squeeze.

SPEAKER_01

No, it is getting repeatedly struck.

SPEAKER_00

Okay, let me see if I can translate this into something we can all picture. If you're trying to conceptualize this difference, imagine wearing a pair of shoes that are like a half size too small.

SPEAKER_01

That's a good way to put it.

SPEAKER_00

That's your muscular static compression. It's a dull, steady ache. You feel the unyielding pressure against your toes all day long, and it never really lets up. Right. But an artery physically expanding and hitting a nerve? What if we compare that to having a fresh, sensitive bruise on your arm and someone taking their index finger and just gently tapping it?

SPEAKER_01

I think that captures the biological reality perfectly. A single gentle tap on a bruised arm isn't going to cause structural damage. The physical force of a single pulse wave expanding an artery is microscopic. But we have to factor in the sheer math of human biology. Your heart beats roughly a hundred thousand times a day.

SPEAKER_00

Wow. That number just completely reframes the whole picture.

SPEAKER_01

Doesn't it?

SPEAKER_00

Because, yeah, if someone tapped their finger directly onto a sensitive bruise on your arm a hundred thousand times in a single day, the area wouldn't just be annoyed. The nerve endings would become so traumatized that eventually even the lightest brush of air would feel like absolute agony.

SPEAKER_01

And the clinical term for that agony is severe hypersensitization. It's the core pathology of a vascular headache.

SPEAKER_00

How does it happen on a cellular level, though?

SPEAKER_01

Well, these nerves are lined with specialized microscopic structures called mechanosensitive nociceptors.

SPEAKER_00

Okay. Nociceptor meaning pain receptor.

SPEAKER_01

Right. And mechanosensitive meaning they evolved specifically to fire an electrical danger signal to your brain the second they detect physical pressure or mechanical distortion. Oh, what so because they're being struck and distorted by an expanding artery tens of thousands of times a day, the nerve just redlines. It reaches a state of severe chronic inflammation.

SPEAKER_00

So eventually the completely normal, healthy pulse pressure of your own baseline blood flow.

SPEAKER_01

Right, a sensation that a healthy uncompressed nerve would completely ignore.

SPEAKER_00

It crosses a threshold.

SPEAKER_01

That's the tragedy of this condition. The nauseceptors are doing their job warning you of physical damage, but the damage is coming from your own heartbeat.

SPEAKER_00

That is just brutal.

SPEAKER_01

It is. Which means when a patient sits in an examination room and says their head is pounding in perfect time with their pulse, they are actually providing the surgeon with a literal map of the physical environment. That specific nerve is trapped inside.

SPEAKER_00

Okay, so if they're handing the doctor a map, where does X mark the spot? Where exactly in the head are these vascular collisions taking place?

SPEAKER_01

Well, the clinical research

The Temporal Trigger Site Explained

SPEAKER_01

identifies several distinct peripheral trigger sites scattered around the skull. But let's focus on the area most notoriously associated with this specific vascular pulsatal compression, the temporal trigger site.

SPEAKER_00

Okay.

SPEAKER_01

This is your temporal region, basically the area just behind your eyes and above your cheekbones. Got it. And the critical nerve structure navigating this specific neighborhood is a branch of the trigeminal nerve called the zygomaticotemporal nerve.

SPEAKER_00

Okay, I know that's a pretty heavy medical term, but if you just take your index finger and trace a line from the outside corner of your eye slightly up and back toward your hairline, that's the general pathway we're talking about, right?

SPEAKER_01

Yeah, that puts you right in the neighborhood. And tracing the path of that specific nerve under a microscope reveals exactly why it's so vulnerable to being crushed.

SPEAKER_00

Because of the fascia.

SPEAKER_01

Exactly. As it travels up the side of the head to provide sensation to your skin, it eventually has to pierce directly through a barrier. That temporalis fascia we mentioned earlier.

SPEAKER_00

That unyielding, rigid wall of connective tissue.

SPEAKER_01

Right. The whole the nerve passes through is microscopic. It's a very tight doorway.

SPEAKER_00

And from what the surgical notes describe, the conflict arises because the nerve rarely gets to go through that doorway alone.

SPEAKER_01

Yeah, we see a major anatomical conflict at this exact junction.

SPEAKER_00

Yeah.

SPEAKER_01

A branch of the superficial temporal artery frequently runs adjacent to this nerve. Oh they share the same crowded real estate. Often they intertwine like vines, or the artery crosses horizontally directly over the nerve, right at the exact microscopic point where they both attempt to penetrate that rigid fascial wall.

SPEAKER_00

So the nerve is essentially caught between a hammer and an anvil.

SPEAKER_01

That is exactly it.

SPEAKER_00

When the artery expands with the systolic pulse wave, acting as the hammer, the unyielding fascia directly behind the nerve acts like an anvil. The nerve has literally nowhere to retreat, so it just absorbs the blow and gets crushed.

SPEAKER_01

The mechanical deformation is unavoidable. Now the temporal region isn't the only place we see this specific conflict.

Other Trigger Sites And Key Clues

SPEAKER_00

Oh, really? Where else?

SPEAKER_01

The notes detail similar vascular collisions at the frontal trigger site, which involves the superorbital and supatrochlear nerves located just above your eyebrows.

SPEAKER_00

Okay, so forehead area.

SPEAKER_01

Right. Arterial branches often cross over those nerves as well, though the crushing force of heavy forehead muscles usually dominates the pain profile in that specific frontal region.

SPEAKER_00

Gotcha. And the research also mentioned the back of the head, right?

SPEAKER_01

Yeah, we see a major bottleneck at the occipital trigger site, located at the base of the skull and the back of the neck.

SPEAKER_00

Okay.

SPEAKER_01

The occipital artery threads its way up through some incredibly dense heavy neck musculature.

SPEAKER_00

Yep.

SPEAKER_01

And it frequently crosses directly over the greater occipital nerve, compressing it with every heartbeat.

SPEAKER_00

Nikes.

SPEAKER_01

But the temporal site, the side of the head, is where the artery is most frequently identified as the primary solitary antagonist causing the pain.

SPEAKER_00

Wait, hold on. I have to ask a practical question here. You're describing anatomical bottlenecks that are microscopic. They're buried under layers of skin, fat, and heavy muscle. If I walk into a clinic with a terrible blinding pain in my temple, and my neck and jaw muscles are incredibly tight from stress, how on earth does a doctor distinguish between a pounding artery and a tight muscle? I mean, they literally share the exact same microscopic space.

SPEAKER_01

It is an incredibly complex diagnostic challenge, and it requires careful detective work.

SPEAKER_00

So where do they even start?

SPEAKER_01

The physician usually starts with meticulous symptom tracking. A muscular tension headache might start as a dull ache in the morning and worsen slowly as the day drags on and your posture deteriorates at your desk.

SPEAKER_00

Right, classic tension headache.

SPEAKER_01

But a vascular headache behaves very differently. It responds rapidly to cardiovascular changes. The clinical notes point out that physical exertion or even a sudden fever causes this specific type of headache to spike violently.

SPEAKER_00

Well, because physical exertion forces your heart to pump harder and faster.

SPEAKER_01

Exactly.

SPEAKER_00

The systolic pulse wave traveling through your arteries becomes larger and significantly more forceful, which means the arterial hammer is striking the nerve that much harder.

SPEAKER_01

The mechanical force increases, so the pain increases. Furthermore, a skilled physician examining the patient might actually be able to palpate or physically feel a prominent superficial temporal artery visibly throbbing right at the nexus of the pain. The gold standard for proving the exact location of the collision involves

Diagnosing With Palpation And Nerve Blocks

SPEAKER_01

diagnostic nerve blocks. The physician uses a highly targeted injection of local anesthetic to selectively numb the specific nerve in question. Say, the zygomaticotemporal nerve we were discussing earlier.

SPEAKER_00

Oh, it's kind of like walking down to the breaker box in your basement when the power goes out. You start flipping switches, turning off the sensory pathways one by one to see exactly which circuit is overloaded and causing the system to crash.

SPEAKER_01

That is exactly how the diagnostic process functions. If the pounding, debilitating pain completely vanishes while that specific block is active, the surgeon has confirmed the exact anatomical corridor where the nerve is being crushed.

SPEAKER_00

They've isolated the circuit.

SPEAKER_01

They have located the exact millimeter of tissue where the hammer is hitting the anvil.

SPEAKER_00

But there is a massive flaw in the breaker box analogy. An anesthetic block is just a temporary snooze button. It wears off in a few hours, the biological switch flips itself back on, the numbness fades, and that arterial hammer is guaranteed to wake back up and resume striking the nerve. So if the nerve block only proves where the collision is happening, what is the actual permanent fix here?

Why Moving The Artery Fails

SPEAKER_01

The overarching objective of the surgical solution is to permanently separate the delicate sensory nerve from the pulsatal pressure of the blood vessel.

SPEAKER_00

Okay, how did they do that?

SPEAKER_01

The surgeon uses the same small, heavily concealed incisions they would use in a cosmetic procedure or to release a tight muscle. But the real complexity happens under surgical magnification. Right.

SPEAKER_00

Once they find that exact point of collision under the microscope, what does this all mean for the artery? Because my first instinct, if I'm looking at a tube pressing on a wire, is just to nudge the tube out of the way. Just move the artery a few millimeters to the left, create a little buffer zone for the nerve, and close up the incision.

SPEAKER_01

And leaving the artery intact and just repositioning it is a very common first instinct, even for some medical professionals. But it ignores the fundamental biological reality of soft tissue. Which is. Soft tissue inside the human body is highly dynamic. It constantly remodels itself over time, and more importantly, it has structural memory.

SPEAKER_00

It's kind of like leaving a heavy garden hose in a mud rut in your backyard. Oh, I like that. Let's say you have a hose running across your lawn and it's been lying in the exact same spot for a year, pressing directly down onto a delicate landscape lighting wire. If you walk out there and simply nudge that hose two inches to the left, you haven't really solved the problem, right?

SPEAKER_01

Right. Why wouldn't moving it solve the problem?

SPEAKER_00

Because the mud has already formed a deep grooved rut around the hose. As the ground shifts over the next few weeks and water pressure pulses through the hose, making it vibrate and move, gravity is just going to pull it right back into that same muddy rut.

SPEAKER_01

Exactly.

SPEAKER_00

It's inevitably gonna slide back down and rest directly on top of the wire again.

SPEAKER_01

That analogy perfectly captures why repositioning fails in the human body. The temporalis fascia and the surrounding tissues in your head have that exact same structural memory. Wow. If a surgeon just pushes the superficial temporal artery aside, the natural tension of the tissues combined with the constant forceful pulsing of the blood wave will cause that vessel to migrate over a few months.

SPEAKER_00

It just finds its way back.

SPEAKER_01

It will slide right back into its original anatomical rut directly against the nerve. So you cannot just move the physical structure creating the pulse.

SPEAKER_00

Which means if you can't move it, you have to snip that section of the garden hose out of the yard completely.

Bracketing And Excising The Vessel

SPEAKER_00

You have to permanently eliminate that segment of the artery.

SPEAKER_01

Yes. The surgical technique detailed in the clinical notes is known as bracketing, dividing, and excising the vessel.

SPEAKER_00

Okay, break that down for us.

SPEAKER_01

Now a surgeon cannot simply cut an active artery or it would hemorrhage immediately. Right, obviously. First, they bracket the troublesome segment. Under heavy magnification, they place secure stops using precise heat cautery, surgical ligatures, or tiny titanium clips at two distinct points.

SPEAKER_00

Okay.

SPEAKER_01

They place one clip just upstream of the nerve crossing and one clip just downstream.

SPEAKER_00

So they isolate and completely seal off that specific tiny segment of the vessel that's causing the problem. Right. And once it's sealed, they divide it and physically excise, meaning they resect or remove that tiny piece of the artery from the patient's head, completely freeing the nerve. Aaron Powell Exactly.

SPEAKER_01

Once the arterial segment is removed, the nerve is thoroughly reinspected under magnification. The surgeon meticulously checks all angles to ensure absolutely no other microscopic vascular branches or tight muscular bands are touching it before the incision is finally closed.

Why Arterial Excision Is Safe

SPEAKER_00

Wait, hold on. Did you just say they cut a piece of an active artery out of the head?

SPEAKER_01

I did, yes.

SPEAKER_00

I have to pause here because if you hear the phrase arterial excision, your brain probably immediately goes to the absolute worst case scenario. Naturally. You hear a surgeon is permanently cutting and removing a section of an artery near your brain, and the immediate fear is that you're cutting off oxygen to your brain or that the skin on your scalp is going to die. I mean, you can't just gloss over removing blood vessels.

SPEAKER_01

No, that anxiety is entirely understandable. And it's usually the first question patients ask. But that fear stems from a common misunderstanding of how our cranial plumbing is actually laid out.

SPEAKER_00

Okay. Clarify the plumbing for us.

SPEAKER_01

Aaron Powell To understand why this surgery is safe, we have to separate the internal circulatory system from the external circulatory system. The massive vessels supplying blood and oxygen to your brain are heavily protected, routed deep inside your neck and skull, and they are completely isolated from the peripheral vessels we're talking about here.

SPEAKER_00

So the superficial temporal artery, the occipital artery in the back of the head, all these tiny vessels at the peripheral trigger sites, they have absolutely zero connection to the internal carotid system that keeps the brain and the eyes functioning.

SPEAKER_01

They have zero connection to the brain.

SPEAKER_00

Wow.

SPEAKER_01

They are terminal branches of the external carotid system. Their sole evolutionary purpose is to feed the soft tissue, the subcutaneous fat, and the skin of the face and scalp. So the brain is 100% safe from this procedure.

SPEAKER_00

Okay, but that still leaves the scalp. If you physically remove a section of the superficial temporal artery to save a nerve, how does the skin on the side of your head survive without that blood flow?

SPEAKER_01

It survives because the human scalp possesses one of the most brilliantly redundant blood supply systems in the entire human body.

SPEAKER_00

Redundant meaning backups.

SPEAKER_01

Exactly. It relies heavily on a biological safety net called collateral circulation. The blood feeding your forehead, your temples, and the back of your head does not arrive through one single isolated pipe. It is delivered by a highly dense overlapping network of arterial branches arriving from all directions.

SPEAKER_00

This makes so much sense. It's essentially functioning exactly like the street grid of a major city. Right. If a water main breaks on a small residential side street, the city dispatchers close down that one single half-block alleyway to fix the pipes. The entire city doesn't paralyze.

SPEAKER_01

No, they just go around.

SPEAKER_00

The cars, or in this case the blood, simply divert to the overlapping avenues, the boulevards, and the adjacent side streets. The traffic distributes itself seamlessly across the remaining grid, and everyone still gets to their destination.

SPEAKER_01

Collateral circulation works exactly like that city grid.

SPEAKER_00

Right.

SPEAKER_01

Excising a small millimeter-long segment of the artery isn't shutting down the interstate highway, it is simply closing an alleyway.

SPEAKER_00

Right.

SPEAKER_01

The surrounding side streets possess more than enough capacity to absorb and redirect the flow of blood to the scalp. And this concept of anatomical redundancy is deeply established in medical practice.

SPEAKER_00

Really? Where else do they do this?

SPEAKER_01

Surgeons in other medical disciplines routinely perform temporal artery biopsies, where they entirely remove large segments of these exact same vessels for testing, with absolutely no damage to the survival of the scalp.

SPEAKER_00

And the surgeon performing this migraine procedure doesn't just cross their fingers and hope the grid handles a detour, right? They visually verify the traffic is flowing.

SPEAKER_01

Oh, visual confirmation is a mandatory step in the operating room. Before closing the incision, the surgeon closely inspects the surrounding tissue. Right. They confirm that the skin color remains perfectly pink and healthy. They verify in real time that the collateral perfusion is actively feeding the area from other directions while the freed nerve is finally allowed to exist in a silent, pressure-free corridor.

SPEAKER_00

Man.

Paradigm Shift And Closing Question

SPEAKER_00

Pulling all of this together, what we're really talking about today is a profound shift in how we view chronic pain. Debilitating pulsator pain is not always just a stress reaction or a muscle spasm you can massage away.

SPEAKER_01

No, it is not.

SPEAKER_00

It can be a literal mechanical anatomical collision. And finding permanent relief requires a comprehensive surgical mapping of everything the muscles, the rigid fascial walls, and these dynamic pulsing arteries.

SPEAKER_01

And this remarkable synthesis of structural anatomy and surgical logic comes directly from the ongoing work of Dr. Adam Lowenstein, MD FACS, at the Migran Surgery Specialty Center.

SPEAKER_00

Such fascinating work.

SPEAKER_01

Truly. For anyone looking to explore the mechanics of these procedures further, or to understand the diagnostic process we outlined, headachesurger.com is a tremendous resource. It provides a deep dive into how isolating and physically removing the mechanical trigger changes lives.

SPEAKER_00

It fundamentally changes how you view the inner workings of your own body. We started this deep dive talking about how a pounding head is used as a metaphor for a stressful day. But for these patients, a trapped nerve is literally misinterpreting the perfectly normal, life-giving rhythm of their own pulse as a violent physical attack.

SPEAKER_01

Which is just incredible to think about. It really is.

SPEAKER_00

Which leaves you with a pretty wild mind-expanding question to ponder long after this is over. Considering how easily a nerve can be fooled by a crowded anatomical pathway, what other perfectly normal, healthy physiological rhythms humming away inside our bodies right now are being completely misread as pain simply because our internal wiring has gotten a little too cramped. Keep that in mind the next time you find yourself rubbing your temple.
