Think hard on it if you consider shoulder surgery. I had a bunch of trash in mine from 10 year old injury. Then I tore the ligament from the collarbone to the shoulder. This gave me bursitis. The doctor offered to remove the bursa and polish up the end of the collar bone "aggressively". Should have stopped right there when he said that....so 3 years later it hurts more often and worse than it did before. It just hurts different now. My right shoulder is an inch or so lower than my left one. The problem is your muscles get all out of whack because the shoulder geometry is different...Okay, anyway.
Helpful tip that sounds obnoxious but is the truth: figure out what makes it hurt and don't do that. Anything that I do that causes numbness or tingling in my hand causes me to switch hands or to take a break. Typing, driving, washing car, etc.
Hope it helps.
