What symptoms characterize iliotibial band syndrome?

Iliotibial band syndrome (ITBS) is primarily characterized by diffuse burning pain located on the lateral aspect of the knee. This condition occurs when the iliotibial band, which runs along the outside of the thigh from the hip to the knee, becomes tight or inflamed, often due to overuse. As a result, athletes and individuals who engage in repetitive activities—such as running or cycling—may experience a specific pain that is felt during movement, particularly when bending the knee. The burning sensation is often exacerbated by activities such as running downhill or on uneven surfaces.

In contrast, symptoms such as sharp pain in the hip, achiness in the lower back, or numbness in the foot do not align with the classic presentation of iliotibial band syndrome. While the iliotibial band can influence knee and hip mechanics, the hallmark of ITBS is the localized discomfort around the knee, specifically the lateral side, making diffuse burning pain the defining characteristic of this syndrome.
