Sciatica after surgery: persistent pain, recurrent disc or another cause?
Leg pain after lumbar surgery may reflect early recovery, recurrent disc herniation, residual compression, scar tissue, instability, another level or a non-spinal cause. Timing and neurological findings guide investigation.
Immediate postoperative discomfort differs from pain that returns after a symptom-free interval. Recurrent herniation is only one possibility; infection, hematoma and nerve injury must be considered when appropriate.
Assessment and decision points
Assessment reviews the procedure, level, symptom-free interval, wound, fever, neurological function and pain distribution. Contrast MRI may help distinguish recurrent disc from scar in selected cases.
| Clinical situation | Possible next step | Why it matters |
|---|---|---|
| Expected early soreness | Monitor recovery and wound | Symptoms should improve. |
| Pain returns after symptom-free interval | Evaluate recurrence | Imaging may change the next step. |
| Fever or rapid deficit | Urgent surgical assessment | Infection or compression must be excluded. |
Management and treatment choices
Stable recurrent symptoms may use medication, activity progression, rehabilitation or selected injections. Revision discectomy, endoscopic revision or fusion may be discussed when recurrent compression, instability or severe functional loss is confirmed.
