Shin Splints

Understanding Shin Splints

Also known as: MTSS, Medial Tibial Stress Syndrome, Runner's Shin Pain Shin splints — medial tibial stress syndrome — is a painful overuse condition affecting the inner border of the tibia (shinbone), where the posterior tibialis, soleus, and flexor digitorum longus muscles attach. It exists on a continuum with tibial stress fracture, which is the more serious end: persistent or undertreated MTSS can progress to a stress fracture, so early, accurate assessment matters more here than with many overuse conditions. Diffuse aching along the inner shin, typically in the lower third of the leg, starting during warm-up and fading as you run, then returning afterward, is the early pattern. As things progress, pain persists through runs and at rest.

Tenderness extends along a long segment of bone — two to three inches or more — which helps distinguish MTSS from the pinpoint tenderness of a stress fracture. New or returning runners, military recruits, and female athletes are most at risk. Soft-tissue work on the posterior tibialis, soleus, and deep calf compartment reduces periosteal tension. Foot, ankle, and subtalar adjustments improve mechanics.

Gait, cadence, and footwear analysis identifies drivers. A graduated return-to-run plan with symptom-based progression rules is essential. We monitor carefully: focal pinpoint tenderness, night pain, or worsening despite rest prompts imaging. Most MTSS cases resolve within four to eight weeks with structured care.

We may recommend: Graston/IASTM, ART, extremity adjustments, mobilization, corrective exercise, orthotics, kinesio taping Seek immediate care if: You develop focal pinpoint tenderness on the bone, night pain, or pain that worsens despite rest — these raise concern for stress fracture.
