Used to be
Just one point - chiropractors are not doctors. Lots of them "claim" to treat CRPS but if you look through all of the clinical and other literature out there on CRPS, you will see an amazing lack of any references to chiropractic treatment - good, bad or otherwise. If it was something that was considered useful from a treatment or therapeutic perspective, I can't believe that there wouldn't be at least some clinical studies, evaluations or articles discussing its effectiveness.

So long as they don't do you any damage when they are doing their manipulation I am sure that it can't do any harm and if you get something beneficial from it then that is most likely a good thing.
