Lumbar disc herniation compressing the nerve roots in the lower back can cause pain in the buttocks and popliteal fossa, which we can refer to as sciatica. The underlying cause is still due to lumbar disc herniation. Generally, over 95% of patients experiencing initial pain can self-heal and find relief from the pain. In terms of sciatica, statistical and evidence-based medical research shows that most patients, especially those who initially exhibit symptoms, generally experience significant symptom relief within three months. However, if symptoms do not improve within three months, surgery is definitely indicated.
