May be a big problem: There are different possible causes for this. A blood clot in the deep vein needs treatment right away. So does a problem with the blood supply to the lower leg and foot. An infection or injury to the muscles can also cause it and needs treatment also. Go to the nearest ER tonight to start the evaluation and begin appropriate treatment if necessary.
