Signs and symptoms of an insect sting include a quick, sharp pain at the site of the sting, often accompanied by pain, itching, swelling and redness. You may see the stinger still embedded in the skin. If the person is allergic to insect stings, the person will show signs and symptoms of an allergic reaction or anaphylaxis.
