Kim i don't know if you believe in alternative medicine or not,I call it complimentary medicine lol, but have you tried any herbal remedies, i can't tell you of any specific one's as i have not tried any myself, but just wondered if any of those might help her pain, i have arthritis myself in my little fingers and it hurts like hell at times,anything might be worth a try eh?

This is a nz website, but i am sure you can get these herbs worldwide.
