Hi bigsanfer....When you say upper arm do you mean your shoulder joint or your tricept where your muscles are. It sounds like you may have arthritis,or some kind of nerve thing going on. I would really ask your rhumy about it with that much going on and being in that much pain. I'm sorry you are goiing thorugh this at such a young age. Debbie
