If you havent gone for physical therapy I stongley recommend it. Therapy is necessary to get you muscles and joints working properly again. If you went straight to work after you could have re-injured your shoulder or damaged the work that was done. I hope all is ok with you.
My shoudler used to dislocate if I sneezed, coughed hard, threw a ball, or even if you hugged me too tight. I couldnt do anything with my right arm. I was is constant fear of the pain from dislocation. I had my surgery in Feb and had therapy from March to May. My shoulder is better than ever. I can lift and throw now. The shoulder will never be the same but I have strenght in it.
Best wishes....
