Leg Pain can be constant or intermittent, develop suddenly or gradually, and affect your entire leg or a localized area, such as your shin or your knee. It can also take a number of forms — stabbing, sharp, dull, aching or tingling. Some leg pain is simply annoying, but more-severe leg pain can affect your ability to walk or to put weight on your leg.
Most leg pain results from wear and tear, overuse, or injuries in joints or bones or in muscles, ligaments, tendons or other soft tissues. Some types of leg pain can be traced to problems in your lower spine. Leg pain can also be caused by blood clots, varicose veins or poor circulation.
