L4-S1 bulging disc means that the nucleus pulposus has bulged out but has not broken through the annulus fibrosus, and the annulus fibrosus has not been completely ruptured, which can be partially cured after standardized treatment, and can usually be treated by general treatment, traction therapy, medication, and functional exercises. 1. General treatment: 3 weeks of strict bed rest, 3 weeks after wearing a waist cuff down to the ground, within 3 months is strictly prohibited to stoop to lift heavy objects or stoop to pick up objects, to avoid lumbar cold. After treatment, the nucleus pulposus can be retracted and the fibrous ring can be healed. 2. Traction therapy: traction therapy includes manipulative traction, pelvic traction, etc. The purpose is to reduce the pressure on the intervertebral discs, promote the retraction of the nucleus pulposus, relax the muscles around the lumbar vertebrae, relieve muscle spasm, and reduce the load on the joints. 3. Medication: Oral non-steroidal anti-inflammatory drugs such as celecoxib and ibuprofen can be taken as prescribed by the doctor, as well as drugs for relieving muscle spasm such as epirubicin hydrochloride, etc. Nutritional nerve medications such as methylcobalamin and vitamin B1 can also be chosen in order to alleviate the symptoms of nerve compression. 4. Functional exercise: daily attention should be paid to the exercise of lumbar back muscles, such as three-point support method, swallow flying and other activities to enhance the strength of the lumbar back muscles and increase the stability of the lumbar spine. Patients with L4-S1 bulging discs should actively cooperate with doctors and actively carry out standardized treatment to improve the symptoms of nerve compression, and some patients gradually recover their health. For patients with poor results of conservative treatment, surgical treatment can also be chosen to alleviate clinical symptoms.
