I researched crps and fibro and the difference between the two is that crps shows physical symptoms as well as constant pain and fibro has constant pain but no physical symptoms. I got fibromyalgia two years after being diagnosed with crps. My dr says crps sometimes triggers fibro.

They are both incredibly painful chronic illnesses but I get so upset when people and drs I know try to compare the two and say that they are the same thing. I can tell you that they are two totally different things. I will agree that they both involve the nervous system.

I'm not a doctor but this is what I've read and what I've lived for the past six long years.
