Lumbar disc herniation and sciatica are closely related to each other. The common cause of sciatica is a herniated lumbar disc that compresses the nucleus pulposus and stimulates the nerve roots, causing damage to the nerve roots that make up the sciatic nerve after the nerve roots have been stimulated, resulting in sciatica. Another rare cause is trauma to the sciatic nerve in the process of travel, muscle adhesions or other causes of compression of the sciatic nerve, which often occurs in sciatica, but accounts for a relatively small proportion. If there is trauma, identified adhesions and muscle contracture, need to target local treatment of sciatica, other unknown causes or no other trauma, sciatica still need to be treated from the symptoms of herniated discs, need to check the situation of lumbar disc herniation compression, take conservative or surgical treatment is better.
