Unless there is a diagnosis, all of this advice is meaningless.
The only good advice given here is to not do anything until you see a doctor, which was your original inquiry, about dealing with your coach.
I am really not surprised, you have come here asking all types of questions, as to what programs suggested, and as far as workouts. I admire you for trying so hard to get better at your position, but do understand that if you really do not know what you are doing, you can hurt yourself.
