I think doctors who really want to help their patients give more than just physical treatment, but also some sort of energetic transferring of whatchawannacallit.
And about the pain physically manifesting itself - Some people believe our existence has three different hmmm let's call it dimensions (can't think of a better word at the moment)-
Thoughts, feelings and sensations - like, brain, spirit/mind, and body.
When our feelings are hurt for whatever reason, it sinks in our very own body, and stays there, until we release it by reaching a higher level of consciousness, through meditation (each one and his own technique, as there are quite a few).
Buddhists call these hurts sunk into our bodies "Sankharas". Once you manage to be deeply relaxed and focused, you can feel the pain in your body, and observe what thoughts and feelings it arises. These are the traumas that created this specific pain in the specific area. The longer the pain stayed there, the harder it will be to dissolve. After a few years of doing this i still have quite a lot of sankharas left. It's worth it though. You feel as if you have freed energy that was stuck as Mass, and you become more fluid and potent gradually.
I have a feeling you do this intuitively however
