For most people taking a shower is pretty common, but for this teenage girl it could be a death sentence. Alexandra Allen suffers from a condition so rare it only other 35 people in the whole world are known to have it. The 17-year-old-girl from Utah is so allergic to water that even sweating can cause a potentially deadly burning rash. She had her first severe reaction to water when she was 12. While on vacation with her family, she went swimming in the hotel pool. Later that night, she woke up itching and covered in hives. Since then, she avoids water as much as possible.
