There are many different risk factors and causes of leg pain. The most common type of leg pain is when you experience overuse or wear and tear of your bones or muscles, or from an injury of the tendon or other soft tissues. Joint pain is another cause of leg pain including arthritis. You may also experience leg pain due to lack of blood flow or circulation. In some cases, leg pain is caused by varicose veins, swollen blood vessels, or blood clots. Excessive pressure on the legs will cause severe pain that requires medical attention. Talk to your doctor if your leg pain persists or gets worse over time.
