Shin Splints

The term "shin splints" refers to pain along the shin bone (tibia) — the large bone in the front of your lower leg. Shin splints are common in runners, dancers and military recruits. Medically known as medial tibial stress syndrome, shin splints often occur in athletes who have recently intensified or changed their training routines. The increased activity overworks the muscles, tendons and bone tissue. Most cases of shin splints can be treated with rest, ice and other self-care measures. Wearing proper footwear and modifying your exercise routine can help prevent shin splints from recurring.

Symptoms

If you have shin splints, you might notice tenderness, soreness or pain along the inner side of your shinbone and mild swelling in your lower leg. At first, the pain might stop when you stop exercising. Eventually, however, the pain can be continuous and might progress to a stress reaction or stress fracture.

Causes

Shin splints are caused by repetitive stress on the shinbone and the connective tissues that attach your muscles to the bone.

Diagnosis

Shin splints are usually diagnosed based on your medical history and a physical exam. In some cases, an X-ray or other imaging studies can help identify other possible causes for your pain, such as a stress fracture.

Treatment

In most cases, you can treat shin splints with simple self-care steps:

• Rest. Avoid activities that cause pain, swelling or discomfort — but don't give up all physical activity. While you're healing, try low-impact exercises, such as swimming, bicycling or water running.
• Ice. Apply ice packs to the affected shin for 15 to 20 minutes at a time, four to eight times a day for several days. To protect your skin, wrap the ice packs in a thin towel.
• Take an over-the-counter pain reliever. Try ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or acetaminophen (Tylenol, others) to reduce pain.

Prevention

To help prevent shin splints:

• Analyze your movement. A formal video analysis of your running technique can help to identify movement patterns that can contribute to shin splints. In many cases, a slight change in your running can help decrease your risk.
• Avoid overdoing. Too much running or other high-impact activity performed for too long at too high an intensity can overload the shins.
• Choose the right shoes. If you're a runner, replace your shoes about every 350 to 500 miles (560 to 800 kilometers).
• Consider arch supports. Arch supports can help prevent the pain of shin splints, especially if you have flat arches.
• Consider shock-absorbing insoles. They might reduce shin splint symptoms and prevent recurrence.
• Lessen the impact. Cross-train with a sport that places less impact on your shins, such as swimming, walking or biking. Remember to start new activities slowly. Increase time and intensity gradually.
• Add strength training to your workout. Exercises to strengthen and stabilize your legs, ankles, hips and core can help prepare your legs to deal with high-impact sports.

There's no way to say exactly when your shin splints will go away. It depends on what's causing them. People also heal at different rates; 3 to 6 months is not unusual. The most important thing is not to rush back into your sport. If you start exercising before your shin splints have healed, you may hurt yourself permanently.
