Like halfbaked mentioned...the more you try hunting with a torn rotator cup (I thought it is called Cup?) any ways the worse your gonna make it...and if you end up getting operated on the longer the recovery time........so don't mess it up worse than it already is Goofy!
I messed my shoulder up at work and there was no way I could pull back my Bow string,ended up getting surgery and I was careful with it for several months,bought a newer bow with more let-off and turned the poundage down low enough to draw back and went out hunting.I never got a Deer within range to shoot my Bow so I didn't strain my shoulder that Fall and was fine the next year for Bow Season.You may want to get a temporary "Crossbow Permit" signed from your Doctor so you can use it temporarly until you heal up if you end up getting operated on?
