I feel somehow, that I must be getting paid back for some terrible misdeed in my youth with these thigh cramps/spasms. For the last year or so I've been periodically tormented with these hellish episodes. The first time it happened I wound up slithering down and off my bed thinking I stood a better chance of working out the cramp on the floor while writhing around clutching my wretched thigh in anguish. It does actually help me to be on a hard flat service while gnashing my teeth and attempting to straighten out the leg.  I guess misery does indeed like company, as I felt strangely relieved to know that I'm not alone suffering from these horrendous cramps. Is there a support group?
