I had crawed across the bed, gotten up and sudden severe cramping pain ran circles around my left leg from the knee up into my lower stomach area. I made it two steps to the wall with severe pain total anxiety when it hit. It subsided where I could move a few steps then hit again, I was in the bathroom. It wasn t quite as severe but still cripling. I made it out of the bathroom but it hit again and I made it into the computer room to sit down. Your talking 12 steps. Each time it subsided I tried to make it to the front door to let my dog out but when I made it to the door I bent over with the cramping again. Severe muscle cramping feeling. Then I made it to the couch and relaxed and the pain subsided. Still had some soreness left from it for awhile but started felling tired and weak and developed a headache which tylonol 500mg doesn t seem to be helping. Nausia right know, 6 hours later with mild headache.
