don't know. check out the arthritis society web pages and contact a chapter in your area. they will likely be happy to share their coping strategies and treatment options.
I don't have rheumatoid arthritis, but I have pain sometimes doing hard work. I usually soak myself in warm/hot water with epsom salt and wintergreen alcohol..
I hope you feel better..
I don't know what to tell you but I can relate to starting to develop arthritis - knees and ankles. Ahhhhh!
