If you have had this issue for a while now i would say that you are not resting as much as you are letting on. Even if you are not training you are still doing things to agrravate the problem. Its a real challenge when you have bursitis because you have to make sure you dont use and overuse your arm in ways that will aggravate the situation, that means no heavy lifting and no bringing your arm up over your head or rotations with your arm. No hitting things because the impact of that just makes things worse. You have to take it easy and get the injections if the pain is too much. PLus i reccomend massage therapy for your whole shoulder girdle,but make sure you get a structural body worker who understands about bursitis and who wont re-injure you. The massage therapy is not going to cure your bursitis but it will help relieve the tension and provide circulatory refreshment to your shoulder girdle as you heal.

It makes me mad when people say I turned and ran like a scared rabbit. Maybe it was like an angry rabbit, who was going to fight in another fight, away from the first fight.
