I was dx by a trip to the ER with burning foot pain. I was at PT at the time and they called the ambulance. It was a result of foot surgery. About four years later I found a pain management specialist who was very familiar with CRPS. I also have Small Fiber Neuropathy dx by two biopsies taken from my leg. It's hard at times to distinguish one from another. My trip with care has been spinal cord stimulators - one implanted in 2012 , another 2018, currently I am on Low Dose Naltrexone and that is taking a lot of pain away. Before that I have had sympathetic nerve blocks that have helped with the rest of pain LDN hasn't helped. The next step for me is RFA of the nerve he blocked.
I too had been without help until the third pain management doctor passed me on. I received a phone call from my current doctor asking me to be his patient. That was 12 years ago. He took me on because he feels everyone deserves the best care and he likes a challenge! I pray you may find that right person.
