Lateral IT Band Syndrome: What to Know

The iliotibial band is a strong strip of connective tissue running along the outer thigh from the hip toward the shin. Repeated knee bending and straightening can irritate the tissues near the outer knee. Pain often builds during a run, especially with hills or longer efforts, and may settle after stopping. Clicking or local tenderness can occur. [Knee Pain](/symptoms/knee-pain/) has many causes, so pain that is constant, swollen, or unrelated to activity deserves a broader assessment.

Reduce the distance, speed, hills, or cycling resistance that triggers pain, then maintain comfortable low-impact movement if it does not worsen symptoms. Rehabilitation may address hip strength, trunk control, cadence, footwear, and training changes. [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) and [Gait Retraining](/treatments/physiotherapy-and-rehabilitation/gait-retraining/) can help identify load and movement contributors. [Sports Massage](/treatments/manual-and-manipulative-therapy/sports-massage/) may ease surrounding muscle tightness but does not replace strengthening. A [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/) is a clinician-led option for selected persistent pain.

Arrange review if pain limits ordinary walking, swelling develops, the knee locks or gives way, or symptoms continue despite reducing the provoking activity. Seek prompt care after a significant twist, direct blow, fever, redness, or rapidly increasing swelling. A clinician can check the meniscus, ligaments, kneecap, hip, and lower back as well as the IT band.

Ask which training change is most useful, whether hip and knee strength are contributing, and how to return to running gradually. Discuss footwear, running surface, pain-monitoring rules, and alternatives if symptoms recur.
