Andy, ignore the Doctor. They are OK for dishing out pills etc. but not that good at actually fixing things. I have specialised in this field and have cured many patients with this problem, usually with one treatment. And they have never had a recurrence. Tennis, hockey, airport baggage handlers and a professional Squash player (world champion at the time), have all recovered immediately and carried on with their sports/jobs. I may not know much about trumpet playing, but I am bloody good at sports injuries.
