Hi Simon

Thx for the info. Perhaps you should copy your post and start a new one and put a link to it here?

In any case, my quick thoughts are:

1. Not from flu jab. I don't have any evidence but they would have to stick it to u in a strange position to get both of those nerves.
2. Probably nerve. Muscle damage usually hurts. So does a fracture.
3. Get GP referral to see a physio and go from there. Either that or a neurologist.

Cheers
