In september i had arthroscopic surgery on my left shoulder. i had labral and ac debridement, bursectomy and decompression. why am i still in pain.?

Shoulder scope: Check with surgeon to make sure no infection or new tears.

Many reasons: The first thing to do is check with your surgeon. Continued pain after a surgery can be from an improper diagnosis, not fully taking care of the problem during surgery, or recurrent tears at the shoulder. Without knowing what you were going in for -- i.e. What was your diagnosis, it is difficult to tell if what was done to your shoulder was the correct thing. Check with your surgeon.
