Epilepsy

[Rotating Rabbit]

When I laugh, and am self conscious about finding something amusing, I get this feeling in my hands rather like if you bang your funnybone/elbow. It continues for a few minutes and I can still use my hands but not very well; I cant close my fist properly and cant use any degree of force e.g. I couldnt hold onto a tennis racket without difficulty. Does anyone else get this or has heard of anyone else who had it? or am I alone in this symptom?
