My rotator cuffs have been bothering me lately. They have been weeker and sometime annoy me so bad i want to rip them off. They dont hurt though just annoy me. I have taken it easy in the gym this week to try and help them and have been stretching them even though sometimes it feels like streching irritates them. I would like to know how to heal them without stopping going to the gym. I am 16 5'8 160 lbs
