A while back I posted about cracking in my shoulders, mainly my left one. I gathered it wasn't a big deal really and just neverminded it. The thing is my left shoulder is constantly in some sort of pain, mild to nagging and once every couple of months or so severe for about a day. Rotator cuff work used to hurt but lately that's subsided and it's comfortable.
The thing is my shoulder doesn't so much "pop" as it does "click." It feels like it's bone on bone. I doubt I can diagnose it by feel like that but I've been thinking about getting a shot if it helps with this sort of problem. Any advice?
