I have fibromyalgia. The pain in my muscles is really bad. Sometimes I have found by keeping my feet and lower legs covered with a blanket at night, that helps keep away the terrible cramps. I use ZanaFlex, a muscle relaxer, and strong pain meds sometimes when I hurt bad. Physical Therphy is great if you can afford it. I leaned how to massage my legs to get the knots out of my muscles and help them to relax. Just taking a day off to relax and do nothing helps me. But it is the coping day to day that gets real old. I just want it to go away so I can go back to work. But it's been over five years without relief so I guess I'm stuck with it.
