After struggling with severe pain in my left shoulder and arm for a couple years I finally went to a chiropractor. It turns out that I have a shoulder spur. He says it's an overgrown bone in the shoulder that needs to be shaved with orthoscopic surgery. Apparently it's occupation related and common in mechanics and electricians. Has anyone had the surgery and how long was your recovery time? A friend of mine had it done and he was out for 7 weeks. I'd like to get best and worse case scenarios because I can't afford to close my shop for 7 weeks.
