There is no absolute best way to eliminate nerve root edema, and it varies from person to person. Generally, infusion of anti-swelling drugs or combination of non-steroidal anti-inflammatory drugs is effective in relieving nerve root edema. Nerve root edema is mainly caused by nerve root compression caused by the irritation of the proliferation of bone or herniated disc and other tissues. In the acute stage, it can be treated by infusion of mannitol, hepatic saponin sodium and other anti-swelling drugs, and the edema of the nerve root can be gradually reduced in a short period of time under normal circumstances. In most cases, nerve root edema is caused by local aseptic inflammation due to irritation and compression. Therefore, in the application of anti-swelling drugs, oral non-steroidal anti-inflammatory and analgesic drugs are also needed to cooperate with the treatment, and commonly used drugs such as celecoxib, bisacodyl, and so on. Drug treatment of nerve root edema has individual differences, so we need to clarify the cause of the disease as soon as possible and timely treatment, do not blindly use drugs.
