There are many websites that talk about how Fibro comes with RSD most often as not.

There are 18 tenderpoints that the Dr. can check you for. Usually a Rheumotologist can diagnose you with it and CFS which also comes with it often.

Devin Starlanyl wrote a good book called Fibromyalgia % Cronic Myofascial Pain Syndrome. You can check it out at the Library and it has great info in it. She says in her book that cramps and diarrhea does come with Fibro. She says it can be caused by the tenderpoints in the stomach area.

I am sure in the websites you will find this info also. As I said there are several that talk about how Fibro and RSD go together many times.

I hope you start seeing better days.
