Hello everyone, had surgery in the summer of 2007 to repair and stabilize my shoulder with an arthroscopy. It was in rough shape and i have severe arthritis in the shoulder. Was in a sling for 6 weeks and my other shoulder started to take the beating and now today I went to lift something off of a shelf with both my arms and my "good" shoulder, the one i did not have surgery on seemed to clunk out and back into place. I've noticed swelling around the shoulder and have been icing regularly, but it just does not feel the same at all since this popping happened. It seemed like i blacked out for the split second that the popping occured, and am very very worried as i do not want to have 2 surgically repaired shoulders ...... any suggestions or feedback on this?? not sure what to do , havent gone to see a doctor yet as it only happened a few hours ago but deeply concerned, thanks. by the way i am just turned 19 years old and was active in high level sports but now very limited
