What to know about shin splints in runners

The term often refers to medial tibial stress syndrome, in which the tissues around the shin respond to repeated impact and muscle traction. Pain may spread along the inner border of the lower leg and appear during or after a run. A sudden increase in distance, speed, hills, or training days can overload tissues that have not adapted. Footwear, running surface, recovery, and strength may also influence symptoms. Pain in one precise spot, pain at rest, or pain that steadily worsens deserves assessment because a bone stress injury can feel different.

Pause or replace runs that reproduce pain with low-impact movement that feels comfortable. Once symptoms ease, rebuild with shorter, easier sessions and change only one training demand at a time. Warm up gradually, keep calf and lower-leg strength progressing, and check whether shoes are worn or unsuitable for your foot. A physiotherapist can review running form, hip and calf control, and your weekly training pattern. Avoid using pain relief to hide symptoms while continuing the same load.

Book an evaluation when shin pain persists despite reducing impact, returns each time you run, or changes your stride. Seek prompt care for pain in a small focal area, pain at rest or at night, swelling, numbness, weakness, or inability to bear weight. A clinician can decide whether examination or imaging is needed before you resume impact exercise.

Ask whether the location and timing suggest shin splints or another cause, which activities are safe now, and how to progress distance, pace, hills, and rest. Ask how strength or gait assessment could reduce repeated overload.
