based on the rest of this thread, no this is not very unusual. Same exact thing happens to me and for some reason is now getting worse now that I'm 30. I'm trying Beta blockers tomorrow. hoping for a good outcome!!
I get this and was told beta blockers work. See if your doc will prescribe this.
I get the rash too and I think mine started from roaccutane as well. im on noten which is a beta blocker but it helps to start with but after a while it's like your body overpowers it and then you semi become dependant on it because if you miss is for one day I'm on edge all day and the smallest thing that wouldn't normally bother me makes me break out in the rash. Have you found and miracle cures yet?
