In some cases, an audible<unk>  or popping noise as the tendon at the<unk>  flexor crease moves from flexion (knee toward waist) to extension (knee down and<unk>  joint straightened). It can be painless. After extended exercise, pain or discomfort may be present caused by inflammation of the iliopsoas bursae. Pain often decreases with rest and diminished activity. Symptoms usually last months or years without treatment and can be very painful. Extra-articular * Lateral extra articular The more common lateral extra-articular type of<unk>  occurs when the iliotibial band, tensor fasciae latae, or gluteus medius tendon slides back and forth across the greater trochanter. This normal action becomes a<unk>  when one of these connective tissue bands thickens and catches with motion. The underlying bursa may also become inflamed, causing a painful external<unk> . * Medial extra-articular Less commonly, the iliopsoas tendon catches on the anterior inferior iliac spine, the lesser trochanter, or the iliopectineal ridge during<unk>  extension, as the tendon moves from an anterior lateral (front, side) to a posterior medial (back, middle) position. With overuse, the resultant friction may eventually cause painful symptoms, resulting in muscle trauma, bursitis, or inflammation in the area. Intra-articular Because the iliopsoas or<unk>  flexor crosses directly over the anterior superior labrum of the<unk> , an intra-articular<unk>  derangement (i.e. labral tears,<unk>  impingement, loose bodies) can lead to an effusion that subsequently produces internal<unk> <unk>  symptoms.
