Progression back into normalcy from my stage?
I originally injured my shoulder at the beginning of this year from weightlifting. I was doing incline pressing and dips one day. I noticed after one session it felt very "sore", but it wasn't painful. I tried to continue workouts on the following days as normal but briefly after that it transitioned into unbearable pain during exercise so I had to stop. At the start, I was having a lot of pain. It hurt to raise my arm vertically, it would always "catch" and "pinch", and I was unable to reach for things on a shelf without pain. I couldn't reach my arm behind my body without pain, and every day I would wake up feeling pain that shoulder. I did go to physical therapy for a brief time where they told me it was likely a rotator cuff issue, and then continued to do those PT workouts at home.
It's been months since then, and almost all of those things have resolved. Lifting my arm without pain is relatively easily, though it does flare up some days. I can reach behind me, and reaching for things on a shelf does not bother me at all. In recent weeks I've actually been able to do more things like chin ups without pain, and even cuban presses with 10 lbs. But still, at this point I can't do a pushup without pain, and light weights on an incline press seem to cause pain in both my front delt/acromium and in the bicep tendon. Is this progression normal after all this time? Should I get an MRI? Just a month ago my PT told me that I was progressing well and making improvements and it's likely unnecessary. But at the same time I do feel far from normal. I am making progress in just about every way, it just seems unreasonably slow. Are there certain exercises I should prioritize at this stage?
