Boss lady heard it from across the room. They figure it got hung up on a calcification and snapped past it creating the wonderful pain and then it just kept hurting from inflammation. I've had a couple days of rest with it and it has reduced. Still sore but it doesn't hurt, if that makes sense. Electrical stimulation, ice therapy, Icy Hot and Tylenol. Wouldn't be so bad, except for being left handed, so it gets more use than it should.
Nothing loose, nothing blocking, but it's starting to sound like my knees...Rice Krispies.
Of course it's your left shoulder. It's the one you use the most, so it gets damaged the most. Righties have stuff go wrong more with their right arms/shoulders.
