Shin Splints Explained
In brief: Shin splints, known clinically as medial tibial stress syndrome, is pain along the inner edge of the shin bone caused by overloading the tissues that attach to it. It is very common in newer runners and in anyone increasing their training quickly or running on hard surfaces. The pain usually develops gradually and eases with rest. Ignored, it can occasionally progress to a stress fracture, so it should not be pushed through.
What are shin splints?
Shin splints is the everyday term for medial tibial stress syndrome, an overuse injury producing pain along the inner border of the tibia, the main shin bone. The pain comes from the muscles, tendons and bone covering being repeatedly loaded faster than they can adapt. It is one of the most common complaints among new runners and those returning after a break.
What causes them in runners?
The leading cause is doing too much too soon, a rapid increase in mileage or intensity before the lower leg has adapted. Running on hard surfaces, worn or unsupportive shoes, and foot mechanics such as overpronation can all add to the load. Tight calf muscles and weak lower-leg muscles also contribute.
Symptoms to recognise
The classic symptom is an aching or tender pain spread along the inner shin, often over several centimetres rather than one precise point. It tends to come on during or after running and ease with rest, at least early on. A sharp, pinpoint pain on the bone, or pain that persists at rest, is a warning sign that should be checked, as it can indicate a stress fracture.
Treatment and recovery
Relative rest is the foundation, reducing or pausing impact running while the tissues recover, with ice to settle a flare-up. A gradual return with sensible mileage progression, supportive footwear and calf strengthening helps prevent a recurrence. Cross-training such as swimming or cycling keeps fitness up without the same impact. If pain is sharp, localised or not improving, see a clinician to rule out a stress fracture.
