For more than four months, a clear, tasteless liquid leaked out of Aundrea Aragon's nose whenever she bent over, but doctors reassured her that it was only allergies.

"It wasn't even dripping, it was pouring out of my nose," said Aragon, a 35-year-old mother from Tucson, Ariz. "If I looked down or bent over, it would literally pore out of the left side of my nose. I had no control at all."

Even though doctors "blew off" her concerns, Aragon said that "deep down," she knew something was seriously wrong.
