What are allergy symptoms?

ANSWER

Congestion, along with an itchy and watery nose and eyes, are allergy symptoms. You'll probably sneeze a lot, too.

Histamine is what sets off your symptoms. Your body sees the thing you’re allergic to as an invader. It sends out chemicals like histamine to fight off the foreign substance.
