"Doctor after doctor told Kendra the fluid coming our of her nose was because of allergies," Nebraska Medicine posted to Facebook.

About five years after the car accident, Jackson visited the ears, nose and throat team at Nebraska Medicine.

It was there that she found out she had a cerebrospinal fluid leak.

In other words, fluid from "HER BRAIN WAS LEAKING OUT OF HER NOSE!" Nebraska Medicine posted.

Doctors discovered that Jackson's brain was leaking about a half-pint of fluid each day, according to WCMH. The leak can be caused by head injuries and brain or sinus surgery, according to John Hopkins Medicine. Untreated leaks can lead to life-threatening meningitis, brain injuries or strokes, according to UTSouthwestern Medical Center.
