Sciatica caused by lumbar disc herniation is mostly due to the herniated disc pressing on the nerve root. First of all, you can try conservative treatment, that is, to take more bed rest, avoid frequent bending, walking with weight, and avoid being sedentary, you can use nerve-nourishing drugs, including methylcobalamin tablets, folic acid tablets, vitamin B6, vitamin B12, etc. for nerve nutrition, which can relieve the numbness and pain of local limbs, and also Mannitol and dexamethasone can be used for sedation, which can eliminate the swelling of the nerve root and relieve the pain. If conservative treatment is not effective, surgical treatment can be tried to completely remove the herniated disc and release the compression on the nerve root, which can relieve the limb symptoms.
