Sciatica

What is Sciatica?
Sciatica refers to pain that radiates along the path of the sciatic nerve — the longest nerve in the body — which runs from the lower back through the hips and buttocks and down each leg. It typically affects only one side of the body and is experienced by up to 40% of people at some point. Sciatica is classified as neuropathic pain — it arises from a direct lesion (usually a herniated disc) compressing the nerve root, causing ectopic nerve firing and loss of normal sensory processing. This explains the characteristic burning, electrical shock-like sensations that differentiate it from simple muscle-based back pain.
Sciatica affects up to 40% of people at some point in their lifetime, with annual incidence rates of 1–5%. It is most common between ages 30 and 50.
Common Symptoms
- Sharp, burning pain from the lower back through the leg
- Numbness or tingling in the leg or foot
- Weakness in the affected leg
- Pain that worsens with sitting
- Shooting pain making it difficult to stand up
- Constant pain on one side of the buttock
Common Causes
- Herniated or bulging lumbar disc (most common)
- Spinal stenosis narrowing the nerve canal
- Piriformis syndrome compressing the nerve
- Degenerative disc disease
- Spondylolisthesis (vertebral slippage)
- Prolonged sitting or sedentary lifestyle

Frequently Asked Questions
How long does sciatica last?
Most cases of sciatica resolve within 4–6 weeks with conservative treatment. However, some cases can persist for months. If pain lasts longer than 6 weeks or is severe, consult a healthcare professional.
What is the best position for sciatica relief?
Lying on your back with a pillow under your knees, or lying on your unaffected side with a pillow between your knees. Avoid sitting for long periods, and when you must sit, use a cushion for lumbar support.
Can sciatica heal on its own?
Yes, most cases of sciatica resolve on their own within a few weeks. Gentle stretching, walking, alternating ice and heat, and avoiding prolonged sitting can accelerate recovery.
What medical procedures treat severe sciatica?
When conservative treatment fails, interventional options include epidural steroid injections (ESIs) — which deliver concentrated anti-inflammatory agents directly into the epidural space to reduce nerve root inflammation. For cases with progressive neurological deficits, a microdiscectomy (surgical removal of the disc fragment compressing the nerve) is the gold standard, typically performed at L4-L5 or L5-S1 with minimally invasive techniques. Clinical guidelines advise against spinal fusion for sciatica unless documented mechanical instability is present.
