Leg pain caused by lumbar nerve compression is mostly seen in lumbar disc herniation, lumbar spinal stenosis, lumbar spine tumor, lumbar spine fracture, etc. Relevant treatments need to be given according to the cause of the disease, such as general treatment, physical therapy, medication and surgical treatment. 1. Herniated lumbar intervertebral disc: It is recommended to rest on a hard bed and apply hot compresses locally. When the pain is severe, pain relieving drugs such as ibuprofen can be given to treat the pain, because it is caused by nerve compression, so methylcobalamin and other nutritive drugs, as well as prednisone and other glucocorticosteroid drugs can be given to treat the pain, and when conservative treatment is ineffective, radiofrequency ablation can be given to surgical treatment. 2. Lumbar spinal stenosis: conservative treatment with drugs such as ibuprofen, methylcobalamin and prednisone, combined with localized physical therapy such as heat and electrotherapy. If the conservative treatment is not effective, surgical treatment such as lumbar decompression can be given. 3. Lumbar spine tumor: lumbar spine tumor can not be cured by conservative treatment alone, but mainly adopt surgical treatment and tumor resection. 4. Lumbar vertebral fracture: the deformation of the vertebral body after lumbar vertebral fracture can cause compression to the nerves, according to the type and severity of the fracture, conservative treatment and surgical treatment can be given. According to the type and severity of the fracture, conservative treatment and surgery can be given.
