An Australian mom was hit by a sneeze so strong it dislocated two vertebrae in her neck.

Monique Jeffrey, 28, said the injury happened less than two weeks ago while she was in bed reading emails on her phone and she let out an "ah-choo."

"I just knew something was wrong. I felt something move and I was in excruciating pain," Jeffrey said.

Fortunately, she still had her phone in her hand. "Help can't move pls call," she messaged her husband Sam.

She was taken to a Melbourne hospital but her left arm developed numbness and tingling.

A neurosurgeon revealed that her top two vertebrae had dislocated and literally jumped over each other.

Jeffrey's head was pressed down on to her right shoulder and locked in that position. Fortunately the injury did not harm her spinal cord or cause neurological damage.

She was fitted with a halo traction, which she will have to wear for up to three months, and weights were used to gradually move the vertebrae back in place.

"I have a 10-month-old baby, my husband and I work fulltime and it only takes something as small as a sneeze to turn it all upside down," Jeffrey said.

"Honestly, who sneezes and does this? Every time I think of it now I laugh, I just can't believe it."
