Hi Bill. Sorry for your continued problems.

Anxiety itself can cause some of the symptoms like dizzy, pulsation, pins and needles. When I get a panic attack I feel very faint, get tingles, my heart beats and I can't think.

As hard as it is, try to calm yourself down. Cut out coffee and fizzy drinks and sugar and take water instead. Get some fresh air and regular exercise as sitting in one position can cause spasms and cramps and pains.

If you're still taking all the high vitamin doses, I would stop and see if it makes a different.

I am not a doctor and don't know any where near as much about any of this as others here, but thought I'd put my tuppence worth in!

Try and do something you enjoy. Thinking about a health problem can just make us focus on it so much that it seems worse - like how things seem worse in the middle of night when it's quiet and we have time to think about things.

Let us know how it goes.
