When you get up in the morning and your buttocks hurt, it may be caused by two reasons: 1. It is possible that the bed board is too hard. When you sleep at night, your buttocks are pressed to the bed board for too long, which leads to local ischemic pain for a long time. 2, it may be a disease of the lumbar spine, such as lumbar disc herniation or lumbar spinal stenosis, lumbar spine slippage and other diseases, which compress the sciatic nerve of the lower limbs, thus leading to nerve pulling in the buttocks. This can lead to nerve pulling pain in the buttocks, and it can also be accompanied by numbness and weakness. In addition to buttock pain, there are also symptoms such as discomfort or pain in the lower back, stiffness in the lower back and nerve pulling pain in the thighs or calves. If you get up and walk in the morning and still have pain in your buttocks, you must pay attention to this condition.
