Shin Splint
En Español (Spanish Version)

Definition
A shin splint is inflammation and pain along the inner part of the lower leg. It involves the shin bone, which is also known as the tibia.

Causes
Shin splints occur when the tissue that connects muscles to the lining of the tibia becomes irritated and inflamed.

Risk Factors
Factors that may increase your risk for a shin splint include:

  • Improper stretching or failure to warm up before exercising
  • Activities that involve repeated pounding of the legs on hard surfaces such as running, basketball, or tennis
  • Increasing intensity of exercise or mileage of running without proper preparation and conditioning
  • Worn-out or ill-fitting footwear
  • Improper running technique or problems with the way the foot hits the ground when running
  • A strength imbalance between two opposing muscle groups in the leg
  • Flattened foot arches
  • Running on a slope
Symptoms
Symptoms of a shin splint include:

  • Pain on the inner side of the shin, described as aching or throbbing with local tenderness
  • Swelling or redness of the shin—not common
Diagnosis
If you have the symptoms of shin splints, you may not need to see a doctor. If the injury does not respond to self-treatment (see Treatments below) after two to four weeks, see your doctor. You may have a more serious injury.

Your lower leg will be examined to look for areas of tenderness and swelling. In addition, the doctor will look for foot problems such as over-pronation.

Images may be taken of your leg. This can be done with x-rays.

Treatment
RICE therapy
  • Rest—Take a break from the activity that caused the pain. This is often enough to clear up the shin splint within several weeks.
  • Ice—Apply ice in 15-minute periods during the first 24 hours and for several days after if needed. Do not apply ice directly to the skin. This helps reduce swelling, inflammation, and pain.
  • Compression—Wearing an elastic compression bandage may help prevent swelling and provide support for the shin and nearby soft tissues.
  • Elevation—Keep the injured leg raised for the first 24 hours, including during sleep. If there is local swelling, this may help.
Medication
In addition to RICE therapy, you may take anti-inflammatory medications to relieve pain if recommended by your doctor. Always use as directed.

Orthotics
If over-pronation is causing your shin splints, you can get custom-made arch supports, called orthotics, which help correct the over-pronation.

Prevention
The following steps may help to prevent the development of a shin splint:

  • Warm up gradually first and then do progressive stretching.
  • Slowly increase the intensity and duration of exercise.
  • Cool down after exercise with light stretching.
  • Run on a softer surface such as grass, dirt, or certain outdoor tracks.
  • Carefully select footwear. Different shoes have different degrees of support and motion control.
  • Avoid over-striding, which can put more stress on your shin.
  • Wear orthotics if your doctor recommends them.
