An Australian mother has broken her neck again after simply laughing at a friend's joke.
Monique Jeffrey, from Australia, was lying in her bed in 2012 when she sneezed which jolted her neck forward and caused the vertebrae to collapse.
After spending 14 weeks in a halo brace, the mother-of-one made a full recovery however five years later Monique, 33, was at work and felt a pain in her neck.
She thought her neck was unstable and when she was in the staff room she laughed at a colleagues joke and it happened again.
Doctors have been left baffled at her injuries, according to the Metro newspaper, and now Monique is recovering from her injuries yet again.
