Allergy Medicine
This is a cruel twist of fate! Some people are allergic to allergy medicine! This allergy is usually related to dyes and other ingredients that come in the medicine. It can be treated by professionals, but is still pretty crazy to think about!
Everything Except Water
Luckily this allergy is incredibly rare, but some people in the world are literally allergic to everything you can eat and drink except water! How awful! Since this allergy is so rare, little scientific research has been done to figure out why it occurs. People that have this allergy suffer from horrible stomach pain and cramps. The boy in the picture is named Kaleb Bussenchutt and he can only eat ice and one specific brand of lemonade. He gets all of his nutrients through a tube that goes directly into his stomach. Can you imagine living that way?
