What are the symptoms of allergies?

The symptoms you get mostly depend on how you are exposed to the allergen. Symptoms of nasal or skin allergy include itchy and watery eyes, sneezing, rashes, hives, and fatigue.

Food allergies can also be identified by stomach cramps, vomiting, and diarrhea. An allergy caused by an insect sting will show redness, swelling and pain at the affected site. Allergic symptoms range from mild to severe.

The most serious reaction is referred to as anaphylaxis, which can badly affect your whole body. Signs of anaphylaxis are hives and itching all over your body, a tight throat, breathing difficulties and tingling in your hands, feet, lips and scalp. More seriously, you may die.
