Does diclofenac sodium work for a herniated disk in the lower back

Diclofenac sodium, as a non-steroidal anti-inflammatory drug, has some analgesic effect on patients with lumbar disc herniation, but the therapeutic effect is limited and only provides pain relief.
Lumbar disc herniation is a condition in which the nucleus pulposus, together with the remaining annulus fibrosus and the posterior longitudinal ligament covering it, protrudes into the spinal canal after the rupture of the annulus fibrosus of the intervertebral disc and presses on the adjacent spinal nerve roots or the spinal cord, resulting in symptoms.
Patients with lumbar disc herniation pain take diclofenac sodium orally to have a certain analgesic effect, but the effect is limited to analgesia, the protruding nucleus pulposus and compression still exists, and can not be resolved from the root cause of the pain. And long-term oral administration will appear many adverse reactions such as: gastrointestinal dysfunction, peptic ulcer, liver and kidney function damage.
It is forbidden for patients who are allergic to this product, have gastrointestinal bleeding or active peptic ulcers, bleeding, history of perforation, liver and kidney insufficiency.
It is recommended to use the drug under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
