System vs Symptom
Aside from a doctor's personality, there is a very distinct difference in how one may be treated, between two types of doctors practicing medicine in the U.S. On the one hand, you have MDs, or Doctors of Medicine; on the other hand, you have DOs, or Doctors of Osteopathy. The Bureau of Labor Statistics provides a sketch of the difference between the degrees here. Each branch of training is equally rigorous and demanding; the emphases are just a little different.
You may ask yourself, does it really make a difference? I maintain that it does. Dr MC, my primary care physician (PCP), is a DO. Had he been my doctor when my blood pressure spiked in 1997, I know that he would have moved beyond "your genetic tendency toward high blood pressure has finally manifested itself", to ask "but why has it done so when nothing else in your life has changed?" And, as time went on, I doubt that he would have blown off my other concerns, as my then-PCP did. Things would be very different for me now, as early detection is the key to improved chance of long-term survival.
I am certainly not saying that all MDs treat symptoms only - it depends, of course, on the physician's personality and approach to medicine and patients. I am saying that it is more likely that a DO will see that symptom in terms of the body as a whole. If the patient is willing to ask questions (and not all are; I just happen to be the elephant's child) an MD might follow up; a DO will follow up.
Go ahead and ask your doctor what training path s/he followed. If you've been seeing that doctor for a long time, you probably won't be surprised by the answer.
