prolapsed disk

A condition that results in the abnormal protrusion (bulging), herniation or prolapse of a vertebral disc from its normal position in the vertebral column. The displaced disc may exert force on a nearby nerve root causing the typical neurologic symptoms of radiating pain (to an extremity), numbness, tingling and weakness. Recurrent episodes of severe back pain are common.

treatment includes non-steroidal anti-inflammatory drugs, corticosteroids and rest. More advanced cases may require surgical intervention (for example laminectomy, micro-disc surgery).
