I had a spur removed from my shoulder a couple years ago. Arthroscopic surgery, hurt like hell for a few days, but I was back shooting with no pain in 2 months. The spurs will slowly cause damage to the muscle groups that make up the rotator cuff, and if left untreated will result in more damage. Motrin, PT and cortisone injections will neer make a bone spur go away.
Im currently doing PT following elbow surgery to clean up and repair tendon damage from cronic tendonitis. it hasnt been fun, but its feeling a lot better, and Ive even shot a few arrows without any problems.
Deciding to have surgery is a tough call,I went to a sports medicine specialist for my elbow,and was well worth it.
