Many athletes get shin splints -- also called tibial stress syndrome -- at one time or another. Whether you jog daily or just had to sprint to catch a bus one day, you may have shin splints when you feel throbbing and aching in your shins. While they often heal on their own, severe shin splints can ruin your game.

Shin splints aren't really a single medical condition. Instead, they're just a symptom of an underlying problem. They might be caused by:

• Irritated and swollen muscles, often caused by overuse.
• Stress fractures, which are tiny, hairline breaks in the lower leg bones.
• Overpronation or ''flat feet" -- when the impact of a step causes the arch of your foot to collapse, stretching the muscles and tendons.

Shin splints are very common. They're the cause of 13% of all running injuries. Runners might get them after ramping up their workout intensity, or changing the surface they run on -- like shifting from a dirt path to asphalt. Shin splints are also common in dancers.

What Do Shin Splints Feel Like?

Shin splints cause dull, aching pain in the front of the lower leg. Some people feel it only during exercise; others, when they've stopped exercising. Sometimes, the pain is constant.
Depending on the exact cause, the pain may be located along either side of the shinbone or in the muscles. The area may be painful to the touch. Swollen muscles can sometimes irritate the nerves in the feet, causing them to feel weak or numb.
To diagnose shin splints, your doctor will give you a thorough physical exam. He or she may want to see you run to look for problems. You may also need X-rays or bone scans to look for fractures. Other tests are sometimes necessary.
