Hey yeah I have the very extreme head sensitivity like you that sets of my pcs a lot worse. I don't have the twitching aspect of it though. It's very odd though, there are days where my head isn't as sensitive and others where if I even go to itch my head to hard I will get disoriented and set off my symptoms. I don't really know how to approach this, all I do is rest. I also eat an anti inflammatory diet and sometimes that seems to help.

Recently, the head sensitivity hasn't been as bad, but it could get worse in the future as the sensitivity seems to randomly worsen. I suggest following marks advice and getting a lot of rest and starting a vitamin regimen and eating healthy
