A bulging disc or herniated disc (also known as a ruptured disc) is the result of pressure upon a intervertebral disc that results in a protrusion from the disc. A bulging or herniated disc can be the result of injury, wear and tear upon the spine from natural aging, or degenerative disc disease.
Simpson was sentenced to nine to 33 years in Nevada state prison but was granted parole on some convictions in July, meaning he must serve at least four more years locked up.
Simpson is currently serving a 9 to 33 year sentence on robbery and kidnapping charges. The former NFL running back was found not guilty of murdering his ex-wife Nicole Brown Simpson and her friend Ronald Goldman on October 3, 1995. Simpson's purported predicament is emblematic of larger problems in America's prison health care system. Specifically, groups like the American Civil Liberties Union have documented instances in which private, for-profit companies are awarded contracts to care for a state's prison population.
