Hi I have been mentioned I think similar to this. I have PN but also RSD. My one pain doctor feels that my pain may be in my brain vs in my spine.The reason is cause I have had some treatments that are supposed to settle the pain but for me increased. So I guess if it is in the brain meds etc that help the brain process pain in a different way can be helpful. Sorry I am not as educated as many here. I saw your other post too and I saw physiatrist. It was actually before I saw my neuro at the very start of my pain. He actually preformed my first emg but then I was sent to the neurologist.Also even if I have where it is in the brain I also have PN from my testing so sometimes I think people can have dual conditions going on. I hope you find relief and answers.
