Sciatica vs Back Pain: How to Tell the Difference — Neurologist Guide Hyderabad

Back pain is one of the most common complaints seen in any neurology or general practice clinic. But not all back pain is the same — and knowing whether your back pain involves nerve compression (sciatica) or is purely muscular or skeletal changes your treatment significantly.

What Is Sciatica?

Sciatica is not a diagnosis by itself — it is a symptom. It refers to pain caused by irritation or compression of the sciatic nerve or its nerve roots (L4, L5, S1, S2, S3). The sciatic nerve is the largest nerve in the body — it starts in the lower back, passes through the buttock, and runs down the back of the leg to the foot.

True sciatica almost always causes pain that radiates below the knee — often all the way to the foot. This radiation pattern is the key feature.

Back Pain vs Sciatica — Key Differences

Feature	Muscular / Mechanical Back Pain	Sciatica (Nerve Root Compression)
Location	Lower back only	Lower back + buttock + leg + foot
Radiation	Does not go below the knee	Typically radiates below the knee
Character	Dull ache, stiffness	Sharp, burning, electric, shooting
Numbness/tingling	Rare	Common — in a specific pattern
Weakness	Absent	May have foot or ankle weakness
Worse with	Bending, lifting, activity	Sitting, coughing, sneezing, straining
Better with	Rest	Walking, lying flat

What Causes Sciatica?

The most common cause (by far) is a lumbar disc prolapse — when the soft inner material of an intervertebral disc pushes outward and presses on a nerve root. The L4-L5 and L5-S1 disc levels are most commonly affected.

Other causes include:

• Lumbar canal stenosis — narrowing of the spinal canal, common in adults over 50
• Piriformis syndrome — compression of the sciatic nerve by the piriformis muscle in the buttock
• Spondylolisthesis — slipping of one vertebra over another
• Tumour or infection — rare but must be excluded (especially with unexplained weight loss or fever)

Red Flag Symptoms — See a Neurologist Immediately

The following symptoms require urgent neurological evaluation — they may indicate serious nerve compression:

• Foot drop (inability to lift the foot while walking)
• Numbness around the groin, inner thighs, or saddle area
• Loss of bladder or bowel control
• Sciatica in both legs at the same time
• Severe weakness in the leg or foot

Diagnosis — What Tests Are Done?

At Sri Anand Child and Neuro Center, Dr. Anand Karnam performs:

• Clinical examination: Straight Leg Raise test (SLR), reflexes, muscle strength testing, sensory testing — to identify which nerve root is affected
• Nerve Conduction Study (NCS): Confirms nerve damage and severity
• MRI of the lumbar spine: Shows the structural cause (disc prolapse, stenosis) — arranged at a nearby imaging centre

Treatment — Most Sciatica Responds Without Surgery

Over 90% of sciatica cases resolve without surgery with:

1. Targeted physiotherapy by Dr. Harisha (MPT) — neural mobilisation, McKenzie exercises, lumbar stabilisation
2. Nerve pain medication — pregabalin or duloxetine during the acute phase
3. Anti-inflammatory treatment — short course for acute disc prolapse
4. Posture and ergonomic correction — prevents recurrence

Surgery (microdiscectomy) is considered only when: red flag symptoms are present, the patient has severe weakness, or conservative treatment fails after 12 weeks of proper treatment.

When to See Dr. Anand Karnam at Sri Anand CNC

Book a neurology consultation if you have:

• Back pain with leg pain going below the knee
• Numbness or tingling in the leg or foot
• Leg or foot weakness
• Back pain that is not improving after 2 weeks of rest
• Any of the red flag symptoms above — urgently
