Herniated Disc: Symptoms, Complications, and When to Seek Care

A herniated disc (slipped/ruptured disc) occurs when the soft nucleus pulposus protrudes through a tear in the annulus fibrosus, compressing nearby spinal nerves or the spinal cord.

Common Symptoms

• Pain: Back, neck, arm, or leg (radiating along nerve path); sharp, burning, or dull.
• Numbness/Tingling: In the dermatome of the affected nerve.
• Weakness: In muscles innervated by the compressed nerve.
• Reflex changes: Diminished or absent deep tendon reflexes.

Serious Complications (Red Flags – Emergency)

• Cauda equina syndrome: Loss of bladder/bowel control, saddle anesthesia (numbness in inner thighs/perineum), bilateral leg weakness — surgical emergency.
• Difficulty walking
• Progressive weakness or paralysis
• Chronic pain (>3 months despite conservative care)

When to Seek Care

• Immediately: Red flag symptoms (cauda equina).
• Promptly: Radiating pain, numbness, weakness lasting >1–2 weeks.
• Routine: Axial back/neck pain not improving with conservative measures.

Most herniated discs improve with conservative care (PT, NSAIDs, time, epidural injections). Surgery (microdiscectomy) is reserved for refractory cases or neurological deficits.
