Lumbar cysts are treated conservatively or surgically depending on the size of the cyst and symptoms. 1. Conservative treatment: If the cyst is relatively small and without any symptoms, it can be treated without special treatment, and the films can be reviewed regularly. If the cyst compresses the nerves, you can apply dehydrating, swelling and nerve-nourishing drugs, such as mannitol injection or methylcobalamin injection. Apply non-steroidal painkillers such as Nimesulide dispersible tablets. 2. Surgical treatment: If the cyst compresses the nerve and the conservative treatment is ineffective, surgical treatment can be adopted, cyst excision + nerve root cuff molding. You can also take interventional tamponade surgery. Lumbar cysts need to go to the orthopedic department of the hospital for further treatment according to the condition. The use of drugs need to follow the doctor’s instructions.
