Much different degrees of pain but similar symptoms from what i know my docs thought i had fibro now i have one saying crps since there is no real treatment or cure for either i guess its a take cymbalta and your pretty much your scewed pat you on the back type of disease

From what I read on fb and Mayo clinic they're different enough

Different

It's complex Regional Pain Syndrome

Honestly, I've never heard of CRPS. I will have to look it up and research it.
