YSK that Medical Doctors are also not Chiropractors. This is why the letters after their names are different. M.D. means Medical Doctor, and D.C. means Doctor of Chiropractic. The major differences in their educations being Surgery, and Drugs for the MDs, and Nutrition, Physical Therapy, Manual Therapy are studied more by DCs. Depending on licensure laws both can order imaging, laboratory testing, and prescribe massage or physical therapy. Also the MD will only have 3-7 minutes to spend with you, and the DC will have much more time to do intake, history, therapy, and to explain what is going on with you and what can be done to improve your situation. Here's a fun fact for ya, some of the injuries attributed to joint manipulation, and this is well documented, were from barbers, kung fu teachers, and yes, MDs and PTs who went to a weekend course in manipulation, instead of the numerous semesters of learning that a DC will have as part of their normal coursework.
@NataliePortland, what's your issue? Why do you care so much about this particular topic?
