Renee,
I replied to your post asking same in another thread:

I don't know of any solutions that haven't already been mentioned. Though the arthritis in my spine is severe (precluding surgery) it's only a nuisance compared to other pain issues. Tonight my knees are bothering me more than my back, but a myofascial spasm in my neck trumps both.
