Leg pain

Leg pain can be constant or come and go. It may start suddenly or get worse over a period of time. It may affect your entire leg or only a specific area, such as your shin or your knee. Leg pain may be worse during certain times, such as during the night or first thing in the morning. Leg pain may worsen with activity and get better when resting. You may feel leg pain as 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.

Leg pain is a symptom with many possible causes. Most leg pain results from wear and tear or overuse. It also can result from injuries or health conditions in joints, bones, muscles, ligaments, tendons, nerves or other soft tissues. Some types of leg pain can be traced to problems in your lower spine. Leg pain also can be caused by blood clots, varicose veins or poor blood flow.

Self-care

Minor leg pain often gets better with treatment at home. To help with mild pain and swelling:

• Stay off your leg as much as possible. Then begin mild use and stretching as recommended by your health care provider.
• Raise your leg whenever you sit or lie down.
• Put an ice pack or a bag of frozen peas on the painful part for 15 to 20 minutes three times a day.

Try pain relievers you can buy without a prescription. Products you put on your skin, such as creams, patches and gels, may help. Some examples are products that include menthol, lidocaine or diclofenac sodium (Voltaren Arthritis Pain). You also can try oral pain relievers such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve).
