Got to ask - are you SURE this needs operating on? You say you've tried physio and you've obviously gone doctor > consultant surgeon route but.......
In my experience, I don't trust physios all that much, doctors are mainly programmed to believe in surgery and surgeons have a vested interest.
Have you tried an osteopath? They always seem far more keen to try and manage the situation and work through it if at all possible. What have you got to lose by giving it a go? It might make the difference between being laid up or coming out for plenty more BGR recce days this winter. Don't know anyone in your area but I'm sure others on here do.
