That is great news, I think? No idea what Bursitis is or how to avoid it but certainly sounds much better than the other things running thru your head!
Avoid inflammatory foods....so diet matters... Stretching and post-work/workout ice is nice. I wear a neoprene sleeve or wrap to sorta "hold things together" when I do dumbell or kettlebell workouts.
Oh...and don't do a lot of physical activity and grow old :D
