Medial Tibial Stress Syndrome (Shin Splints)

Common Symptoms

• Aching or sharp pain along the inner (medial) border of the shin bone
• Pain that's typically diffuse along a stretch of bone rather than one sharp point, a key difference from a stress fracture
• Pain that initially occurs during exercise and eases with rest, then progressively occurs earlier in activity or persists afterward
• Tenderness along the inner shin when pressed
• Symptoms tied to a recent increase in running volume, a surface change, or new/worn footwear

Why It Happens

Medial tibial stress syndrome is thought to result from repetitive traction and bending stress on the tibia at the attachment of muscles and connective tissue along its inner border, combined with bone remodeling that hasn't kept pace with training load. It sits on a continuum with tibial stress fractures — essentially the same repetitive-overload process, with shin splints representing an earlier, more diffuse stage than a focal stress fracture.

Why It Can Become Persistent

Because running and walking both load the tibia with every step, the area gets very little true rest during normal daily activity, and training errors (increasing mileage or intensity too quickly) are a leading cause of both the initial onset and the tendency for shin splints to recur when athletes return to training before the tissue has fully adapted.

Who Commonly Gets It

This is extremely common in runners, especially those increasing mileage rapidly, as well as military recruits and other athletes with a sudden jump in repetitive impact activity. Risk factors include worn or inappropriate footwear, running on hard or cambered surfaces, and certain foot mechanics.

How It Is Usually Diagnosed

Diagnosis is usually clinical: pain and tenderness along a several-centimeter stretch of the inner shin, without the sharply localized point tenderness more typical of a stress fracture. Imaging (MRI or bone scan) is used when a stress fracture is suspected instead of, or in addition to, shin splints, since the two require different levels of caution with continued activity.

Traditional Treatment Options

• Activity/training-load modification: Reducing mileage or intensity temporarily, often with a structured, gradual return.
• Footwear evaluation: Assessing whether current running shoes are appropriate and adequately supportive for the individual.
• Physical therapy: Addressing calf and foot strength, running mechanics, and gradual load progression.
• Cross-training: Maintaining fitness with lower-impact activity (cycling, swimming) during the recovery period.
• NSAIDs: Sometimes used short-term for symptom control.

Why Someone Might Start Looking for Another Option

Shin splints are notoriously prone to recurrence when runners return to training too quickly, and the standard advice — rest and gradually rebuild — can feel unsatisfying to athletes mid-training-cycle, which leads some to look into additional options that might be used alongside a structured return-to-run program.

Where Shockwave Therapy May Fit

A 2024 systematic review of shockwave therapy in athletes found it may be useful as an adjunct to exercise-based treatment specifically for medial tibial stress syndrome — one of a small number of conditions the review specifically named as having supportive evidence in an athletic population.

How Shockwave Treatment Works for This Area

Acoustic pressure waves are directed at the tender area along the inner shin. This is intended as an adjunct to — not a replacement for — appropriate training-load modification, since continuing to aggravate the area at the same volume is unlikely to resolve regardless of any adjunct treatment.

What the Treatment Feels Like

Most patients describe a firm tapping or pressure sensation along the shin, with some tenderness during treatment over the sorest areas.

What Happens During Your First Visit

Your visit begins with a provider evaluation focused on your history and a physical exam relevant to your complaint. If shockwave therapy is determined to be clinically appropriate, your first treatment can typically be provided the same visit. See our What to Expect page for the full walkthrough.

Who May Not Be Appropriate

• Suspected tibial stress fracture (sharply localized point tenderness, night pain, or pain with hopping on one leg), which needs imaging and more cautious management than shin splints alone
• People who have not yet had a medical evaluation to distinguish shin splints from a stress fracture
• Active infection, open wounds, or certain bone conditions at the treatment site
• Certain circulatory, neurological, or bleeding-related conditions, per your provider's screening

This list is not exhaustive. Your provider will screen for contraindications during your evaluation.
