Neurologists and pain management doctors are the two primary ones to diagnose and treat RSD or CRPS. The "better get over this or I will end up with CRPS" comment is clearly made by someone who knows nothing about CRPS because that's not how it works. However...early diagnosis and treatment can be crucial to getting the condition under control and in remission. Definitely follow up with the neurologist and see a pain management doctor with experience treating CRPS. Learn what you can about the condition so you can accurately gauge whether the docs you talk to know what they are talking about or if they are as uninformed as your previous doctor.

I will pray that you do not have it but if you do then that one off hand, idiotic remark, may well have put you on the right path for treatment at a time when early treatments may do wonders for you. Good luck.
