I have pn in my legs and arms along with diabetic gastroporisis but now am having an issue with red and burning skin from my collar bones up...just red enough to look like a light sunburn.....it is not continuous but may be red and burn for a day or two then gone a few days...just seems like the type issue that pn involves but neither my gp or neurologist seems to have a clue....thought someone on this board might have run into similar issues and would appreciate any info.....
