Hi I have both PN and RSD though my pain doctor and neuro feels the pain is the RSD. Well for me I had an emg/nc that showed I have PN. My pain doctor was saying how with PN though sometimes there is a reason behind it where if you treat that the PN can get to a better point. With RSD it is about pain management though PN has pain management too. Not sure if I am making sense here. I have seen so many doctors and none have made the connection between the RSD and PN. Not to say they are not but just my experience.
