Sciatica
Sciatica is pain that travels along the sciatic nerve, from the lower back through the buttock and down the leg. It is a symptom rather than a disease, most often caused by a herniated disc or spinal stenosis pressing on a nerve root. It is very common, and most episodes improve without surgery.
What are the symptoms of Sciatica?
- Pain radiating from the low back or buttock down the back of the leg
- Burning, electric, or shooting quality to the pain
- Numbness or tingling in the leg or foot
- Weakness in the leg or foot in more significant cases
- Pain often worse with sitting, coughing, or sneezing
What causes Sciatica?
Sciatica is a symptom rather than a diagnosis: it means the sciatic nerve, which runs from the lower back down each leg, is being irritated or compressed. The most common cause is a herniated disc pressing on the nerve root, but a narrowed spinal canal (stenosis), bone spurs from arthritis, or a slipped vertebra can do the same. Less often, muscle spasm deep in the buttock or, rarely, a tumor is responsible. Age, extra weight, prolonged sitting, diabetes, and heavy lifting all raise the odds.
When should you see a specialist for Sciatica?
Most sciatica improves within weeks using relative rest, movement, physical therapy, and medication, so non-surgical care comes first. Seek prompt medical attention for progressive leg weakness, numbness in the groin, or bladder or bowel changes. If significant pain persists beyond six to twelve weeks despite good conservative care, a spine surgeon can discuss whether a procedure like microdiscectomy or laminectomy would address the cause.
How is Sciatica treated?
Common questions
Does sciatica always need surgery?
No, the large majority of cases resolve with time and conservative care. Surgery is typically considered only for persistent, severe symptoms with a clear compressive cause on imaging, or for progressive weakness.
How long does sciatica last?
Many episodes improve within four to six weeks, though some take a few months. Recurrences are common but often milder and shorter.
What triggers sciatica?
The most frequent causes are a herniated disc or age-related narrowing (stenosis) pressing on a nerve root. Prolonged sitting, lifting, and twisting can aggravate symptoms while the nerve is irritated.
