I don't know if this is the problem, but you might talk to your rheumie to find out if it is muscle related or not. My hands and arms and calves are tight and tense all the time. my rheumie has had me try a new product, a topical gel form of Voltaren, a muscle relaxer. It has given me great relief in my arms and hands, though I don't have a lot of joint pain, mostly muscle stiffness and hardness, not being able to open my hands up all the way and stuff. Even if the Voltaren gel isn't the right thing, they are coming out with lots of meds topically that we normally take in pill form and there may be something topical like a topical form of a stronger prescription antiinflammatory that might get the medicine right where it's needed and save you some stomach trouble! The new topical stuff is great. I can't take Voltaren because of my liver but can use the gel, and it works better, in my opinion, because it goes right where you need it. It actually did work on my knees, which have nondamaging form of AI arthritis and the voltaren gel worked. I use it at night and don't wake up from knee pain anymore.
I hope you feel better and find out. Maybe you can call your doc and talk to the nurse and mention what's going on and they can help you. I also use a lot of bengay, and Absorbine horse linament for joint pain.
