I strongly doubt that chiropractic will permanently favorably affect your RSD but you may get some temporary palliative relief. I don't believe it would hurt to try. Like anything else is health care, give it 4 weeks, if you find no value, either temporary or gradual, then it's not for you. I would only continue after 4 weeks if you were sure it was helping. Some chiropractors like MD's, PT's or anyone else for that matter in health care, will have you continue to return so long as they have a mortgage or car payment to feed.
