It doesn't sound like a typical case of CRPS but that doesn't mean it's not. What helps mine is heat, meditation, staying as active as possible and meds. I saw you say you couldn't take nerve pain related meds as they made you suicidal - which one(s) have you tried? Gabapentin and I don't get along but Lyrica is fine. Unfortunately by refusing these you may get a red flag from pain management. I would suggest asking for a muscle relaxer as it can help.

My regimen is this: lyrica, celebrex, butrans patch on schedule with tizanidine and hydrocodine as needed. I also use lidocaine patches. The butrans patch is the most helpful currently so I would highly recommend that. I hope this helps.
