sharp burning pain on the outside of my knee that gets worse after running two miles
Summary
Sharp, burning pain on the lateral (outer) side of the knee that flares up during repetitive activity like running is often related to friction or tension in the connective tissues. This specific timing—appearing after a consistent distance—usually suggests an overuse issue rather than a structural tear.
Most likely causes
- Iliotibial (IT) Band Syndrome: The most common cause of lateral knee pain in runners, where the IT band rubs against the femur bone.
- Lateral Meniscus irritation: Sensitivity in the cartilage on the outer side of the knee joint.
- Gluteal weakness: Weak hip muscles causing the knee to "cave in," putting extra stress on the outer knee.
- Bursitis: Inflammation of the small fluid-filled sac that cushions the joint.
