Lumbar disc herniation can be treated with an injection, which mainly uses caudal epidural steroid injections. This approach has a certain therapeutic effect but is limited. For example, it may relieve the patient's pain for about a week, after which symptoms may gradually reappear. I believe that this treatment method is more about addressing the symptoms rather than the root cause. For ineffective conservative treatments, such as resting on a hard bed, applying local heat, minimizing prolonged sitting, and lying down as much as possible except for going to the toilet or eating, symptoms will generally gradually alleviate over about 10-14 days. This can be combined with drugs that promote blood circulation and relieve pain, and drugs that nourish the nerves, as well as some diuretic drugs to relieve the pressure on the intervertebral discs. This can alleviate the stimulation of the nerve roots by the nucleus pulposus of the intervertebral discs, affecting nerves from L4 to S3, which may cause numbness and pain in the back of the thighs, the dorsum of the calves, or feet. The symptoms vary depending on the stage of compression but the difference isn't significantly large. For cases where conservative treatment or injections are ineffective, we can consider interventional surgeries like ozone nucleolysis, which are currently performed skillfully with minimal damage and quick recovery. You can consult a hospital for more information.
