At one time of my rsd I was having migraines and severe head pressure and pain. I get them a little today. I had another brain mri at that time but I think mine is from my severe eye pain. Are you seeing a pain doctor? Have you had an mri? Are you on any new meds?I am sorry about your gp. I have seen 3 gp since my rsd over 3 years and all have been clueless about this condition.
