*And to think it all started with a headache.

I always worry whenever I have a headache, especially if it lasts more than a day and seems to come out of nowhere. This wasn’t always the case. People get headaches all the time for a variety of reasons. Stress. Hangover. Sinus. Allergies. But I no longer make the assumptions I used to make about headaches. Especially since over the years I have learned about fatalities associated with them.

So when I heard this story about a woman who had gone swimming in Oklahoma, and a day or so later was hit with a severe headache; and that headache was no ordinary headache because it got worse, and eventually took her life, I said, “Oh sh*t. My nightmare. A headache killed this woman.

The grieving family of 24-year-old Elizabeth Knight has now set out to warn others because they say it is what their daughter would want them to do.

Knight’s death came as a result of a bacteria ID’d as a “Brain-eating Amoeba” (learn about this in the video).

Beth had taken her kids for a fun day at Lake Murray, but a few days later she became ill. “Her roommate said she woke up stumbling through the house. She was incoherent,” her mother told the media, who says Beth was first diagnosed with bacterial meningitis. But as her health began to further deteriorate, doctors dug deeper into her history.

“The history of her having exposure to freshwater swimming and Lake Murray freshwater lake and that was the first time that primary amoeba encephalitis was brought up,” Beth’s father said.

The amoeba is said to travel up the nose and through the brain.

The bacteria associated with this brain eating amoeba, according to the video below, can be found in ponds, lakes, rivers, hot springs, warm water runoffs from industrial plants, aquariums, soil, and POOLS NOT TREATED WITH CHLORINE.

Although the first case of the bacteria was said to have been identified in Australia, in the U.S. the bacteria, which lives in warm waters as hot as 113-degrees Fahrenheit,  can be found in southern and southwestern states such as Florida and Texas…and now Oklahoma.
