What should you know about endoscopic microdiscectomy?

A surgeon guides a narrow endoscope to the affected area, usually in the lower back, and removes disc fragments that irritate a nerve. The disc itself is not usually removed in full. The aim is to ease nerve-related symptoms such as radiating leg pain, tingling, or weakness when examination and imaging support the diagnosis.

It is different from an injection: an operation physically removes material, while an epidural steroid injection delivers medicine around a nerve. Endoscopic access may reduce disruption to surrounding tissues, but suitability depends on the disc position, spinal anatomy, symptoms, and the surgeon’s experience.

Before surgery, share your medicines, allergies, previous operations, and any bowel or bladder changes. Follow the team’s instructions about eating, drinking, and medicines. Afterward, walking is often encouraged in short, comfortable periods, while lifting, bending, and twisting are limited until your clinician gives a clear plan.

Keep the wound clean as instructed and attend follow-up. Physiotherapy may help restore movement, trunk strength, and safe body mechanics. Improvement in leg pain can occur before numbness or weakness settles, so rehabilitation should match your examination rather than symptoms alone.

Contact your surgical team promptly for fever, increasing wound redness or drainage, worsening pain, or new weakness. Seek emergency help for new loss of bladder or bowel control, numbness around the inner thighs or genitals, or rapidly progressing weakness in both legs.

Ask which nerve is being treated, what improvement is realistic for your symptoms, which activities need temporary limits, and how recurrence or persistent numbness would be handled.
