I think its a great idea... googling can be frightening.. sharing on here is different, kind of comforting i think, to realise weird symptoms being experienced are not just peculiar to yourself !!!!
Dyan i too have the tightening feeling in my head that you described, it petrified me the first time it happened and i waited all day for something dreadful to follow... needless to say it didnt

I actually had it myself today, its a really strange sensation isnt it.
I get aches and pains in places i never thought possible sometimes the whole of my body aches down to my fingers and toes, I can hardly move, all my muscles feel bruised and sore.... there are very few days when i feel what i class as "me"
To be fair the list of "weirdys" is endless !! and all very scarey and confusing

thank goodness for this forum.
love to you all ..... and a merry and symptom free Christmas
