Mother breaks her neck again

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.
