I'm 15 years old, 154cm, and 52kg with no known medical conditions. However, I was believed to be allergic to breast-milk when I developed jaundice after drinking breast-milk as a baby. Since young, whenever I ate shellfish my throat and inner ears would start itching very badly. It would start hurting too, but not in the same way as a sore throat. It sort of feels like a burning sensation deep in my throat. Therefore I have always avoided eating shellfish. Just last night after eating dinner, my throat started burning and itching in that exact same way. Is this some kind of allergy? And should I be concerned about it? Thank you very much. :)
