causes of pain in legs
A strain is a common cause of leg pain and results from increased activity that leads to overstretching of a muscle. While muscle strains usually cause mild soreness, a person may also experience cramping, weakness, and swelling. More sudden or severe injuries can cause a muscle tear which is significantly more painful.
A serious and potentially life-threatening cause of leg pain is known as Deep Vein Thrombosis (DVT). A DVT is a clot in a leg vein that can break off and travel to the lungs. Symptoms of a DVT in the lower leg often include swelling, warmth, and/or redness of the calf.
