Try neurology. I was first diagnosed with allodynia, then my next visit they brought in 2 of the top neurology specialists and they diagnosed me with CRPS type 1… then they referred me to 2 different pain management specialist who confirmed the diagnosis. I would start there because a lot of doctors still don’t even know what CRPS/RSD means or how to help so they won’t do much to help you and most think you’re making it up or it’s a mental thing so they won’t really care. But google neurologist that have experience with CRPS and Chronic or Neuropathy specialist in your area. Hope this helps because the pain sucks.
