I was atwork last night and my calf started cramping up, so i drank tons and tons of water....Any one know what caused this?? It is now 11 hours later from when it started and I still cant walk properly as my left calf is just in pain. I dont know wheter it is cramping of if i tore my calf....THere is no bruising, or any abnormal signs of a tear. The only thing is that when i try to stretch the calf it starts to hurt. Also it hurts when i apply pressure to it with my hands..
