The treatment of acute lumbar disc herniation mainly includes bed rest and application of dehydration drugs, as follows: 1. Bed rest: After lumbar disc herniation, the patient is required to rest on a hard bed, in a supine position, with a pillow at the waist, and in principle, absolute bed rest. The so-called absolute bed rest means lying flat on the bed at all times except for eating, sleeping and going to the toilet, and minimizing the time spent moving on the ground. 2. dehydration drugs: use dehydration drugs as soon as possible, such as mannitol, dexamethasone, sodium hepaticoside, horse chestnut seed extract tablets, etc., which are commonly used in clinical practice. By eliminating the edema of nerve roots through dehydration, the inflammatory pain-causing substances around the nerve roots disappear, and the patient’s back and leg pain symptoms will be reduced.
