RE: Bum Shoulder
I have fairly severe Shoulder tendonitus - and someday I will have to have surgery to correct the problem - both shoulders - but the left one is worst too. When I practice with bow - I now practice less often - but with more purpose. I may shoot 3 times a week still - but only 12 or 18 shots per session. I take every practice shot like its on a deer. When I hunt, I take 1000mg ibufrofen when I wake.
I've had seasons when my arm hung like dead meat - it sucks! If your doctor like mine says there is no "quick fix" - Don't over-do the practice - if you hurt the shoulder more - you'll be more apt to develop bad habits and/or not be physically able to pull off a shot when it counts.
