IT band syndrome: meaning and usage for runners
IT band syndrome is irritation around the outside of the knee or hip linked to the iliotibial band during running.
Example
Example: A runner feels a sharp ache on the outside of the knee after 20 minutes, especially on downhills, and it eases after stopping.
Why it matters
IT band symptoms can be confused with general knee soreness, but the location and downhill trigger often point to a different load-management problem.
How runners use it
Reduce painful running, avoid downhill repeats for now, and review strength, cadence, shoes, and recent mileage jumps. Seek qualified care if symptoms repeat.
