Post shoulder dislocation surgery pain.

Hi, I had a dislocation 3 years back, after a some physiotherapy I was back to normal life within 3 months, last year I had multiple socket ball popping out instances, as a precaution and suggestions from multiple doctors I went for Arthosocopy for labrum tear repair with anchorless sutures, post surgery I followed the instruction of using sling for 2 months post that physiotherapy. But I am still struggling with constant shoulder and biceps pain, I am not able to perform day to day activities smoothly, the range of shoulder is about 75 percent, I can feel the stiffness while doing most of the motions. I had lot many suggestions from different doctors prior surgery, but I am not sure what went wrong and what should I do to be normal. Looking forward to proper help and solid course of direction for speedy recovery and normal functioning.
