Causes of pain above the hip include lumbar muscle strain, sacroiliitis, ankylosing spondylitis, etc. 1. Lumbar muscle strain: injury caused by ageing, excessive exercise or labor, unintentional trauma, etc. Inflammation is formed and stimulates the peripheral nerves, which is manifested as pain and aggravated by cold and exercise. 2. Sacroiliac arthritis: Inflammatory reaction caused by fungal infection, joint abnormality, endocrine abnormality, etc. After constant friction and long-term stress, the smoothness of the joint surface decreases, resulting in dull pain above the buttocks and below the waist, and stiffness of the sacroiliac joints in the morning. 3. Ankylosing spondylitis: mostly seen in family genetics, bacterial infections, etc. Typical manifestations are pain above the buttocks, limitation of turning over at night or in the morning, and weakness in the lower back. In addition, lumbar disc herniation, lumbar spinal stenosis and other compression of the sciatic nerve may also lead to pain above the buttocks, which varies greatly from individual to individual, so it is recommended to go to the hospital to find out the cause of the disease.
