The only things that I can do when I get those hard spasms in my legs is to get out of bed and walk them off. Even though I take Zanaflex, I still get enough spasms to wonder if I need to take something other than that. I also get spasms in my fingers and wrists and lower arms which take about 5 minutes to get rid of. They bend my fingers at 90 degree angles from the middle knuckle, and even stretching them out straight almost gives as much pain as the leg spasms. I don't know what causes the spasms in my hands, unless it is just where the spasms like to habituate. I have more spasms there than in my legs. Time and massage is the only thing that I have found that works.
