Lumbar disc herniation can be dehydrated to reduce swelling after the acute phase. Lumbar disc herniation, or lumbar disc herniation, is a common and frequent disease in spinal surgery and is a common cause of lower back pain and low back pain. Lumbar disc herniation develops due to degeneration of the lumbar disc (composed of the nucleus pulposus, annulus fibrosus, and cartilaginous plate), along with partial or total fracture of the annulus fibrosus. The herniated nucleus pulposus irritates or compresses the nerve root and cauda equina, which is a syndrome and a common clinical degenerative disease of the spine. After the acute stage of lumbar disc herniation, there may still be localized swelling and pain, and non-steroidal anti-inflammatory drugs such as ibuprofen, diclofenac sodium and meloxicam can be chosen for anti-inflammatory and analgesic purposes. When the presence of neuroedema is considered, mannitol can be fed intravenously for dehydration treatment to reduce edema and relieve symptoms such as low back pain and numbness in the lower limbs. Patients with lumbar disc herniation are advised to seek prompt medical attention for a definitive diagnosis and targeted treatment. In addition, all of the above drugs should be taken under the guidance of a doctor and should not be used without authorization.
