Two nights ago I was awakened by what I thought was a Charlie horse in my right thigh. What happens next is what concerns me, it was a circular cramping sensation that crawled up my leg. It started in my calf then to the back of my knee in which I could not bend then proceed up to my inner thigh. I was in tears, it hurt so bad! I never experienced a feeling like that before. I am obese with varicose veins. Just thought you might have an answer for me and should this get immediate attention. I do not have any insurance at the moment, not til April. Thank you for your time. Debbie
