A lumbar herniated disc is generally less likely to compress the nerve roots on both sides when the condition is relatively mild; if the condition gradually worsens, it may compress the nerves on both sides. If the condition is relatively mild, the herniated lumbar disc may compress the nerves, but seldom compresses the nerve roots on both sides. Most patients compress the nerves on one side, so symptoms such as lumbar pain and lumbar pain will occur during activities. In most patients, the degree of lumbar disc herniation will gradually decrease after regular treatment, and the condition can be controlled. If the lumbar disc herniation is more serious, it may press on the nerves on both sides, and in serious cases, it may press on the buttocks, thighs, calves and ankles, thus causing hip pain, calf pain, thigh pain and so on. Herniated lumbar discs should be treated in a timely manner and reviewed regularly to assess the prognosis based on the degree of progression of the condition. If the symptoms are severe and conservative treatment is not effective, timely surgical treatment, such as nucleus pulposus removal, can be performed to relieve nerve compression as the principle of treatment.
