I was playing today in about 35 degree temps and was in my 3rd game and was running to get to a ball and all of a sudden I felt a sharo pain in the back, middle of my right calf. It felt like I was shot. I went down immediately and had to limp off the court and take a forfeit. Does anyone have any experience with this type of injury? Did I snap or tear something? Any idea how long I will be away from tennis? Right now I am RICE-ing it and staying off the leg. I might need to get crutches or something to get around a little easier.
