MTSS is a treatable condition. Contact your doctor if you think you may have MTSS.
The exact cause is unknown. MTSS is called an overuse injury. It most commonly occurs from repetitive motion or stress at the shins. Causes may include:
- Acute inflammation of structures in the calf
- Chronic compartment syndrome
- Chronic trauma to structures in the calf
Factors that may increase your chance of MTSS include:
Participation in repetitive, high-impact sports:
- Racquet sports
- Military recruits
- Female runners with amenorrhea (absent menstruation) and osteoporosis
- Pronation of feet (feet turn inwards), or other leg or foot abnormalities
- Poor (hard) running surfaces
- Poor footwear
- Overtraining or recent increase in workout or miles run
- Heel cord tightness
MTSS may cause:
- Shin pain at a very specific point
- Pain when running which gets more severe with continued exercise
- Pain when bearing weight on the leg
- Pain after changing workout intensity or running surface
- Symptoms may not go away with rest
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Diagnosis can be made on this information.
You may be referred to a specialist. For example, a sports medicine physician focuses on sport injuries.
MTSS is treated with:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Crutches may be given for severe pain
- Arch supports and shock-absorbing insoles may be recommended
- When you feel better, slowly return to normal activities—increase your activity level slowly over several weeks
Your doctor may suggest a different pair of shoes . A brace or walking boot may also be needed.
To help reduce your chance of MTSS:
- Wear shock-absorbing insoles when running or during other high-impact exercise
- Stretch before and after exercising
- When starting a new sport or increasing your workout, do so gradually
- Choose footwear that is best for the activity and your foot
- Cross train
