What are allergies to insect stings?
When you are stung by an insect, poisons and other toxins enter your skin. It is normal to have some swelling, redness, pain, and itching around the sting. But you may have an allergic reaction if your immune system reacts strongly to allergens in the sting.
You probably will not have a severe allergic reaction the first time you are stung. But even if your first reaction to a sting is mild, allergic reactions can get worse with each sting. Your next reaction may be more severe or even deadly.
