It is possible to cure leg numbness due to nerve compression by a herniated lumbar disc. This condition is often due to the compression of the sciatic nerve root after a herniated lumbar disc, resulting in abnormal sensation in the sciatic nerve travel area of the lower extremity, commonly occurring in the lateral calf and dorsal foot. If it is the first attack and the herniation is not serious, the corresponding treatment can be carried out through conservative treatment, such as traction, massage, wearing a lumbar brace for protection, braking and resting, and treatment to reduce nerve root edema and eliminate nerve root inflammation can be taken, including oral diclofenac, veritin, root pain level, etc. Oral nerve-nourishing drugs, such as methylcobalamin, can also be taken for corresponding treatment. Generally, the effect is very good for patients with mild herniation and the first episode. If the herniation is very serious after CT or MRI examination, and in severe cases, the nucleus pulposus will fall into the spinal canal causing compression, surgery is needed.
