What causes pain in the buttock crevice?

Pain in the buttock crease, clinically referring to pain in the pelvic bone joints, may be caused by non-disease factors or disease-related conditions such as trauma or gluteal fasciitis. The specific causes are analyzed as follows:

1. Non-disease factors

Prolonged sitting without movement due to work, or intense physical activity, can easily lead to muscle tension in the buttocks and cause pain. Symptoms are generally relieved through local heat application or massage to reduce muscle tightness.

2. Disease-related factors

1) Trauma

When the buttocks suffer external impact or sports injuries, the bones around the buttock joint area may become damaged, leading to pain. If no fracture has occurred, symptoms can be alleviated with adequate rest and local ice application. In cases of fracture, medical treatment at a hospital—including fracture reduction—is required to improve symptoms.

2) Gluteal fasciitis

After an aseptic inflammation develops in the gluteal fascia, inflammatory irritation of muscles and tissues near the buttock joint can also cause pain. It is recommended to take anti-inflammatory and analgesic medications such as diclofenac sodium sustained-release tablets, acetaminophen tablets, or ibuprofen sustained-release capsules under a doctor’s guidance.

In addition, similar symptoms may also result from lumbar disc herniation, piriformis syndrome, ankylosing spondylitis, hemorrhoids, anal fissures, perianal abscesses, eczema, psoriasis, or perianal tumors. If symptoms persist for a prolonged period, timely medical evaluation and diagnostic tests are necessary to identify the underlying cause and initiate appropriate treatment.
