What are the opinions of all your doctors about excercise? Mine always looks very worried when I tell her about exercise I've been doing. I get the feeling she would rather me do less than more. She definitely doesn't encourage it at all.
I've relaxed my exercising habits over the last few weeks. After a particularly rigorous shoulder/back workout my back kind of hurt for a few days, so I'm ready to calm down now. Don't think it was arthritis related, just a minor injury. I think I'm just so happy I can move again that I was on the verge of over-doing it.
