If painful symptoms occur in the soft tissues near the gluteal cleft, consider whether it is an acute injury such as a local contusion or strain, which can occur after excessive activity or local impact. Relatively severe lumbar sprains can also cause pain near the hip fissure, mainly due to the stimulation of the epiglottic nerve. Patients with inflammation around the sciatic tuberosity may also experience pain in this location. The continuous pressure on the hip from prolonged sitting can cause damage or inflammation of the soft tissues and bones around the hip. For example, sciatic tubercle bursitis or peri-sciatic tubercle inflammation can cause pain in the soft tissues around the buttock cleft. Pain in this location should also be considered as a result of anorectal disease, such as fistula or sinus tract, or other similar infectious diseases. If the pain is not significantly relieved for more than 3 days or continues to worsen, you should go to a regular hospital promptly.
