Butt pain can be caused by sciatica, or it can be caused by a lumbar disc herniation. Sciatica is usually caused by a herniated lumbar disc, which can compress and irritate the sciatic nerve, causing sciatica, hence the symptom of buttock pain. If buttock pain is accompanied by radiating pain at the root of the thigh, it may be due to lumbar disc herniation, which compresses the sciatic nerve, thus resulting in buttock pain. However, there are many reasons for buttock pain, not necessarily due to sciatica and lumbar disc herniation. For example, prolonged sitting and standing for a long time, chronic exertion or exposure to cold can lead to muscle tension in the buttocks or soft tissue contusion in the buttocks, which may result in the formation of aseptic inflammation and the symptoms of buttock pain. When the symptoms of buttock pain appear, you should go to the hospital in time for a clear examination and treatment under the guidance of the doctor.
