Gluteus maximus pain may be caused by trauma, lumbar disc herniation, pyriformis syndrome and so on. 1. Trauma: If the gluteus maximus muscle is hit by external force, it may lead to soft tissue injury of the gluteus maximus muscle, resulting in gluteus maximus muscle pain, which may also be accompanied by activity limitation. 2. Lumbar disc herniation: clinically, after the occurrence of lumbar disc herniation, due to the compression of lumbar vertebrae, it will produce obvious pain, and the gluteus maximus muscle may also produce tugging pain. 3. Piriformis syndrome: some patients with piriformis syndrome will experience pain in the gluteus maximus muscle, which also radiates to the calves and feet, resulting in numbness and weakness in the lower limbs. If there is obvious pain in the gluteus maximus muscle, it is recommended to consult a doctor in time for examination and treatment.
