The treatment of herniated lumbar disc edema includes medication as well as surgery. If it is in the early stage of herniated lumbar disc, medication can be administered. First of all, mannitol can be used, which can be 125 ml, twice a day, to dehydrate the edematous nerve, thus relieving the edema of the nerve. The next step is to use a small amount of glucocorticoids, such as dexamethasone or methylprednisolone, in small doses for a general course of treatment of 7-10 days. At the same time, we should use nerve-nourishing drugs, such as methylcobalamin injection or adenosine cobalamin injection. This will nourish the peripheral nerves, thus allowing a good recovery of the function of the compressed and edematous nerves. If conservative treatment is not effective, surgical incision can be considered to relieve the edema of the nerve by relieving the compression of the nerve.
