Shin Splints(MTSS)
Here’s what’s going on:
Shin splints — medically called medial tibial stress syndrome (MTSS) — are an overuse injury that causes pain along the inner edge of the shinbone (tibia).
They happen when the muscles, tendons, and bone tissue around the shin become irritated, usually from repetitive stress like running, jumping, or sudden increases in activity.
Common causes/ risk factors
- Rapid increase in training intensity or mileage
- Running on hard or uneven surfaces
- Worn-out or unsupportive footwear
- Flat feet or very high arches
- Sports with frequent stopping and starting (basketball, soccer, tennis)
Typical Symptoms
- Dull, aching pain along the inside of the shin
- Pain that often starts at the beginning of activity and eases as you warm up — but can return afterward
- Tenderness or mild swelling in the lower leg
If pain persists or worsens, it’s worth checking for stress fractures or other causes, since they can feel similar but require different management.
