Wait a minute, I meant 11 weeks ago when the event occured playing rugby, what advice were you given then about resting / what not to do or physio? Nothing? Did you move the arm and shoulder during these 11 weeks or were you somehow part-immobilized? I'm thinking of physiobobs comments as to "..........in the UK healthcare environment" Sad but true, although there are lots of excellent actors in the NHS show patients are often left under assessed, under informed under treated.
Do see if you can speed up the physio appointment. You have some good links to look at from physiobob. Swot up a bit on relevant parts of your shoulder so you understand what's involved and ask all the questions that are bothering you. Let us know what happens.
