Obviously you have lots going on and have been having medical issues for a number of years. I think it's dangerous to self diagnose from the Internet so I would strongly recommend that you seek a medical specialist to review your history and symptoms. No doubt your GP or PCP can arrange an appropriate referral to a specialist who is most likely to be be a pain management physician, a rheumatologist or a a neurologist.

I'm in no place to say whether you do or don't have CRPS but to be honest, from what you have written it doesn't entirely sound as though it quite fits the diagnostic criteria for CRPS. Contrary to much popular belief, there are very specific diagnostic criteria for diagnosing CRPS. There have been revisions and changes to these criteria over the years as research has advanced and changed understanding of the condition. It can be a very difficult condition to diagnose so its important to be referred to a knowledgable specialist. It could be something else entirely so you want to be sure that you get the right diagnosis and then treatment if that is an option.

All of the individual clinical signs and symptoms associated with CRPS are also shared by countless other conditions so it is a bit risky to try and self diagnose. That said if you are diagnosed with the condition, at least you have a label for it and may be able to look at a more coherent package of therapies.

I wish you good luck
