I get Charlie Horses nightly. Usually in my feet, that run up my leg . After stretching I get muscle spasms in my legs. When I get out of bed to try to stretch the muscle my foot usually is clumped up and when I put it on the floor I crunches. I don't have patasium or magnisium disorders. Those test came back negative. It usually occurs when I am sleeping or have my legs raised resting. Sometimes it occurs in my arms when I get up and stretch them, but those are less severe. I tried a med for RLS and that didn't work at all. It was as if I hadn't then anything. What can I do? I can go with 5 hours a night sleep, but the nights I get only 3 to 4 hours are really ruff the next day.
