Shoulder Exercises for Shoulder Separation (AC separation)

So I had a little bike accident last weekend and suffered a grade one AC separation (aka shoulder separation, though grade one means the ligaments weren't actually torn).  I have plenty of time to heal and be fine for IMLP thankfully.  Since the doctor I saw didn't recommend any strength stuff to help my shoulder heal, yet 4 others have said that there are specific exercises I should be doing (and continue to do as the ligaments were permanently stretched), are there any doctors/PT types etc. that have any recommendations?
