When at first they don't succeed, show them how to do it! When doctors offered no answers, a teen diagnosis herself in science class

When doctors didn't give a Washington state high school student the answers she wanted, she took matters into her own hands.

Eighteen-year-old Jessica Terry, brought slides of her own intestinal tissue into her AP science class and correctly diagnosed herself with Crohn's disease.

"It's weird I had to solve my own medical problem," Terry told CNN affiliate KOMO. "There were just no answers anywhere ... I was always sick."

For years she went from doctor to doctor complaining of vomiting, diarrhea, weight loss and stomach pains. They said she had irritable bowel syndrome. They said she had colitis. They said the slides of her intestinal tissue were fine, but she knew that wasn't right.

So when local pathologists stopped in to teach students in her Biomedical Problems class how to analyze slides, the high school senior decided to give her own intestines a look. And what she found surprised herself and doctor's who missed signs for years.

Here is Jessica's story from CNN affliate KOMO.
