Thanks for the reply. My symptoms are similar to yours, although I haven't had the numbness. Was referred to A and E yesterday for an ECG to make sure it's not my heart causing the shooting pains (it's not) and was told it's probably a nerve blockage (could have told them that, but I guess they are correct to get everything checked). Now awaiting x-ray results. I think mine is probably arthritis connected (runs in the family).
Hope you are feeling a little better now after your op (and that I don't have to have one, lol).
