Is it pain from spacicity (sp?) in your legs?
I found that a heating pad sometimes does the trick. I use one that I can control how hot it gets and how long it's on so I don't overheat myself. I also found that when temps drop below freezing, it has a tendancy to get worse for me.
Sometimes getting more potassium can help a little. (sorry if I spelled that one wrong too, one of those days, lol) Bananas and yogurt are what I use.
Hope the doc can help you out and you feel better soon.
