I am sorry you are dealing with this,, I have a lot of sensory stuff,, just going to a different room with a different temp sets it off,, starting to trip a lot also,, like you its coming on fast,, they dont have a clue whats doing it,, had all the blood test,, been to Mayo,, Nothing,,, only a Dx of (some) small fiber neuropathy,, life sucks like this,,
