This is a standard diagnosis in chiropractic medicine, not in regular medicine. It can be overdone, as they claim it as a cause for almost everything. I do not go to doctors, unless the Lord specifically tells me, but I personally believe the theory is sound, and I know people who swear by chriropractic. I see no harm in trying, as long as the doctor is properly licensed, and takes the necessary safety steps, as any licensed professional would do.
