Disregarding the OP and the unhelpful replies, including mine. You have had some excellent help, nobody wishes you ill, we've all had injuries, some bad, some awful. Yours does sound bad, your approach was all wrong. Lots of people here have a lot of knowledge in different areas.
I appreciate you don't want to go into too much detail, but as you were comfortable to see your doctors, what harm can come from this anonymous website? Post some pictures of your shoulders, edit your face out.
Maybe if we can't help you initially, your post may help someone else in the future.
