Leg pain can be due to a muscle cramp, an injury, atherosclerosis that blocks blood flow in the arteries, blood clot from prolonged bed rest, infection
of the bone, inflammation of the leg
joints by arthritis or gout, varicose veins, or nerve damage due to diabetes, smoking or alcohol drinking.
Try to rest as much as possible and elevate your leg. Apply ice for up to 15 minutes and gently stretch and massage cramping muscles. Pain relievers can also relieve the pain.
