LBlack14 Stop it!! That's the main reason I don't sleep, or try to sleep, in my bed for very long anymore. My right one, literally, feels like it pulls out of socket and gets stuck. I then have to manuever it back in and that hurts like a mutherfucker. It does it when I'm just sitting in my chair too, just not as often. I can't sleep on my back in a bed.
It's worth it. I went from can't use my right arm for nearly anything to being able to play catch with the grandsons. My right shoulder joint was bone on bone and inflamed chronically. Shit was keeping me up a night, couldn't do chores, play golf etc. 12 weeks after total replacement.......good as new. That was 7.5 years ago.
