I'm thinking disease. Just last November I found out that I was allergic to Z-Pack pills. Who knows what other Antibiotic I'm allergic to. In fact, my allergic reaction to those pills gave me Stevens Johnson Syndrome. Its a really really rare illness that only like 20,000 people in the U.S get a year. The Doctor at the hospital told me after the illness was gone, that it was her first time ever seeing someone with it. I looked up the illness after and I got lucky. I only got Pink Eye and Open Mouth Sores as my symptoms. You could get blisters all over your skin or Organ Failure which can lead to death. [spoiler]I also couldn't brush my teeth for 2 weeks because of the Mouth Sores. I felt disgusting and instantly went to a dentist after the Sores were gone.[/spoiler]
