I have a lot of pain in my left shoulder. It frequently clicks and pops and sometimes feels like it is dislocated. I have to lift it and pop it back into place every day after it makes a loud cracking noise and shifts downwards. I lift it with my right arm and push it back up until it cracks, which hurts, but then it feels better. I had an X-ray, and my doctor says it is not serious, but it hurts and is not normal compared to my other shoulder.
