Hi Jimbob, i totaly get where your coming from, this is one of my symptoms ive been remembering from way back to age 14. i do believe in the auto immune problem and believe my gluten allergy has alot to do with mine.
you've prob already read about Ramsay Hunt syndrome, as it can cause heaps of damage to the brain, with out ever showing up with all the GB symptoms. it can attack the brain and cause damage similar to MS.
so your on the right track, good luck to you . jen from Australia.
