It's OA, Doc. The right shoulder, my pulling shoulder, is definitely worse, but it sounds like I've got gravel in both of 'em. I do have terrible genetics and taking the pounding from being a college basketball player didn't help matters much. It's really bad in my back and knees too. Fortunately, with 16 hours of A and P with a goodly bit of exercise science/kinesiology on my college transcript, I can do most of my own PT.
If it weren't for that, along with naprosyn and glucosamine/chondroitin tablets, I'd probably fall apart.
