18-year-old Jessica Terry suffered from stomach pain, diarrhea, vomiting and fever for eight years. She often missed school and her doctors were unable to figure out the cause of her sickness. Then one day in January someone was finally figured out what was wrong with Jessica. That person was her. While looking under a microscope at slides of her own intestinal tissue in her AP science class, Jessica noticed an area of inflamed tissue called a granuloma, which is an indication of Crohn's disease. "It's weird I had to solve my own medical problem," Terry told CNN affiliate KOMO in Seattle, Washington. "There were just no answers anywhere. ... I was always sick."
