Just seeing this. I am a Doctor of Physical Therapy, I agree with Awais. Came here to say my son dislocated his shoulder playing lacrosse and tore his labrum ( usually once you dislocate your labrum gets torn and you will have chronic instability) the pain is interesting it makes me think there is nerve or additional tendon involvement. Definitely would do a stabilization program with a physical therapist, get an orthopedic evaluation and BPC 157-TB-500 was very helpful in my sons shoulder recovery pre and post surgical repair. I think there is a pep with TB-500, BPC-157 and cartilax that may also help. I don’t have personal experience with that
