Symptoms of Sciatica

Sciatica's hallmark is pain that follows a specific path — starting in the lower back or buttock and radiating down the back of one thigh, sometimes continuing into the calf or foot.

Typical Symptoms

• Pain ranging from a mild ache to a sharp, burning, or electric-shock-like sensation
• Numbness or tingling along the same path
• Muscle weakness in the affected leg or foot
• Pain that worsens with sitting, coughing, or sneezing

Symptoms are usually one-sided, affecting only one leg at a time.

How Severity Varies

Some people experience mild, intermittent discomfort, while others have severe pain that makes standing or walking difficult — severity doesn't always correlate directly with how serious the underlying cause is, which is part of why persistent symptoms are still worth evaluating even if they're "just" uncomfortable rather than agonizing.

Warning Signs That Need Urgent Care

Loss of bladder or bowel control, numbness in the groin or inner thighs (saddle anesthesia), or rapidly progressing leg weakness are rare but serious signs of cauda equina syndrome, a surgical emergency.
