That sucks man! It's crap like this that makes people lie about their injuries when they go to the doctor.
I've gone to the doctor or hospital so many times with wakeboarding related injuries (blown knee, concussion, ear infection, tendonitus, etc., that I no longer mention wakeboarding in any shape or form to the doctor. All of my injuries come from the trampoline or the swimming pool.
I guess you could say that I'm a little paranoid that my insurance company will ammend my policy to not include wakeboarding injuries.
