Had RTSA 3 1/2 months ago and it may have dislocated

My RTSA recovery seemed to be going well. Had formal PT for 2 months up until 3 weeks ago. Recently having new pain with activity, and the shoulder doesn’t “look right”. I think it may have dislocated.
I have my 4 month checkup with my surgeon in a week, and will find out then. In the meantime time, does anyone know if there’s a possibility of a non-surgical fix for a dislocation? Like immobilization in a sling? Rather than revision surgery?
