Compression of the lumbar dural sac due to a herniated disc is a relatively common clinical imaging diagnosis. If this condition is found, the need for treatment is determined by the patient’s clinical symptoms. The dural sac is located in the spinal canal and the spinal nerve travels within the dural sac in the spinal canal. A protrusion of the lumbar disc to a certain extent to the posterior will cause compression of the dural sac, and in milder cases, the compression may be simple discomfort in the lower back. Cases like this can be treated conservatively. Usually you can carry a lumbar girth and pay attention not to bend excessively. You can consider the treatment of external application of Chinese medicine, traction, physiotherapy, tui na, acupuncture and other methods. The external application of Chinese medicine can make the protrusion, nerve root and surrounding tissues’ congestion, edema and other sterile inflammatory reactions subside and relieve the pain. In addition to the above methods, non-steroidal anti-inflammatory drugs, such as ibuprofen extended-release tablets and ereciclib, can also be taken orally, together with nerve-nourishing drugs, such as methylcobalamin capsules. If the compression is severe enough to cause compression of the spinal nerve, resulting in radiating pain, numbness, weakness, difficulty walking, intermittent claudication in the lower extremities, or incontinence, or sensory disturbance in the perineal area, surgery is necessary to relieve the compression.
