I've been to a chiropractor, and he really did help me. He improved my condition more in 30 minutes than 3 weeks of PT had. Obviously a lot of problems cannot be cured by popping your back, but good chiropractors can usually help a variety of problems, regardless of their location. Not all of these "quacks" will tell you they can help you when really all they want is your money. My dad had one guy tell him after one treatment that he should probably go up to the hospital because he didn't think he could help him.
Why all the hatin' in chiros?
