coletaterbug,
Have you tried heat to treat the pain in your legs?
I use an electric throw blanket on my legs. I was a little leary at first because I am heat intolerant but the heat from the blanket didn't bother my MS and helped the pain in my legs.
I have been doing this for a few years and even had to get a new electric throw this past fall because the other one wore out
I am sorry you ar in so much pain, I know how that feels
