UNITED NEWS INTERNATIONAL (UNI) — The next time you blow your nose, think about Kendra Jackson.

She recently discovered her constantly runny nose was caused by brain fluid leaking through a hole in her skull.

Jackson told KETV News in Nebraska she started coughing, sneezing and blowing her nose a couple of years after a bad car accident in 2013.

She said she hit her head — hard — on her car’s dashboard.

Jackson told KETV her nose ran “like a waterfall, continuously.”

Doctors told her she had allergies.

But earlier this year, specialists diagnosed the 52-year-old woman with cerebrospinal fluid leak.

Around half a pint of the watery fluid surrounding her brain was spilling through a tiny hole between her skull and nostrils likely caused by her car accident.

Surgeons fixed the hole last month.

A spokesperson for Nebraska Medicine told The Washington Post May 8 Jackson is now “doing extremely well.”
