I'm having servere shoulder blade pain in my left shoulder. I'm 16 and varsity qb for the highschool here so I get banged up a bit and am in good physical shape. Anyways, one day in the gym I was doing squats with the bar on my back below my neck like your supposed to and while driving up to rack the bar my shoulder popped from the weight and it was terrible pain. It hurts to breathe deep or move my right arm (throwing arm) across my body. And same for my left arm. It especially hurts when I swing my right arm across my body and stop it suddenly. I've tried shock therapy, stretching,hot baths, etc. Please help. My team needs me back throwing ASAP
