raynaud's syndrome
"It most definitely works at stopping my attacks when the cold hits. I used to have attacks all day, even if I just opened the refrigerator to take out the milk my hands would turn white. However, I get really bad muscle spasms. Mostly on my legs, but can be all over. I only take it when the temperature is cold and I know I will be outside watching a sporting event. I just started taking it again this week and have been getting muscle spasms in my jaw and behind my ribs as well as my calfs. It is the old things that allows me to be outside to watch my kids games so I will use it on a limited basis."
