Imaging tests found that two people with herniated discs can lead radically different lives: One spends his days popping painkillers, the other waltzes through life. In a well-know

9、n study, researchers checked 98 healthy people: Two-thirds had abnormal discs even though none complained of pain.

15、004, the US Food and Drug Administration (FDA) approved the first such disc, the Charite, for patients with degenerative disc disease.
