I was hanging Xmas lights at the entrance to a subdivision. No where to grab I placed my arm against a wall to step up to a 2 1/2 foot wall. When I pushed to hoist myself up I felt to pops on my left shoulder. I thought after ice and heat it would go away in a few days. It's been couple of weeks and the pain is still there. Some days and nights worst then others. I'm concern of possible tears and how long I have before it's too late to repair. I have to wait until after the new year before I can have any surgery, if needed.
