Medial Tibial Stress Syndrome: The Real Cause Behind Your Shin Splints

If you’ve ever felt a dull, aching pain along the inner edge of your shinbone after running or walking, chances are you’ve experienced Medial Tibial Stress Syndrome (MTSS) — commonly known as shin splints. While many people casually refer to any shin pain as “shin splints,” MTSS is the most common clinical diagnosis behind this discomfort, especially in athletes and active individuals.

Symptoms

The hallmark symptom of MTSS is pain along the inner side of the shin, usually in the lower two-thirds of the tibia. The pain often starts as a mild discomfort during or after physical activity but can progress to a more constant, throbbing pain if ignored. Unlike a stress fracture, the pain from MTSS typically spreads over a broader area and doesn’t occur from a specific point impact.

Causes

MTSS is caused by repetitive stress on the tibia and the connective tissues that attach muscles to the bone. This excessive strain leads to inflammation and microtrauma. Common causes include:

• Overuse or sudden increase in activity

• Poor biomechanics or flat feet

• Inadequate footwear

• Running on hard or uneven surfaces

When muscles and tendons can’t absorb the shock of impact properly, that stress is transferred directly to the shinbone, leading to pain and inflammation.

Risk Factors

Certain factors can increase your likelihood of developing MTSS:

• Beginners who start intense exercise programs too quickly

• Athletes who engage in high-impact sports like running or basketball

• Individuals with flat feet or abnormal gait mechanics

• Wearing worn-out or unsupportive shoes

• Infrequent stretching or improper warm-ups

Prevention

Preventing MTSS involves taking a proactive approach to training and foot health. Here are a few key strategies:

• Gradually increase the intensity of your workouts

• Invest in high-quality, supportive footwear

• Use orthotics if you have flat feet or biomechanical issues

• Incorporate stretching and strengthening exercises for your lower legs

• Cross-train to reduce repetitive impact on the same muscles

Don’t Ignore the Pain

MTSS is manageable if addressed early. Left untreated, it can lead to more serious issues like stress fractures or chronic pain.
