The month of Iyar is not only a month of renewal of the trees, flowers and all growing things, it's also a time of rejuvenation and renewal for animals and man, this is way the acronym of "אייר" is "I am G-d who heals you."
G-d's healing is unique, G-d's healing is לא אשים עליך, I will protect you from being unwell in the first place.
The Talmud says that a doctor functions as a conduit to G-d's healing, and therefore not only heals but prescribes behavior that will ensure good health, so there is no need for healing.
A doctor is merely a channel for G-d's healing.
Two things doctors must remember to be that appropriate vessel:
One, a doctor must put all kinds of bias and selfish motives out of the picture and merely focus on the benefit of the patient. This is a standard customary precept that doctors vow to uphold. A doctor also needs to pray to G-d to have that clarity to perform medicine appropriately.
The perfect approach to medical care has to be predicated on the following paradigm, "I am only doing a mission for the true healer of all flesh."
The second thing that doctors must be conscious of is the spiritual welfare of their patients. Although the patient has merely requested for assistance with the body, a doctor must endeavor to heal the soul as well, as this will enhance the health of the body too.
This is obvious in certain circumstances, like when a doctor prescribes a diet of what a patient should or shouldn't eat, the doctor must empower the patient to overcome the urge of the palate.
The bottom line is that in medical care, the theme of this month, a Jew must connect to G-d and feel where the healing is coming from. Doctors too must focus on how they're merely an emissary of G-d and that the healing of the body is connected to the enhanced health of the soul.
