Please seek the advice of a trained health care professional to determine the cause of your leg pain. The causes of leg pain can vary in severity. The most serious, and potentially dangerous can be phlebitis --where a blood clot may become dislodged and move elsewhere in your body. You may also have a pinched spinal nerve, or simply an electrolyte imbalance which causes muscle contractions. The most effective treatments for each of these causes will be different.
