Just thought I should wrap this thread up by saying that my doc had no answer to what was causing the numb head, but I'm pretty sure it was linked to prednisone withdrawal. Every time I went down another mg it would get worse, then slowly improve over the next 2 weeks before I dropped down again.
It seemed to be harmless. I have been on the pred for over a year so hardly surprising that there are some undesirable effects!
