It's rare to be allergic to fire ant stings, but if you are, you'll need to get medical treatment immediately. Swelling and pain are normal, but if you have these symptoms, get to an emergency care center or hospital immediately:  Hives, itching and swelling in areas other than the place where you were bitten. Nausea, vomiting or diarrhea. Tightness in the chest and difficulty breathing. Swelling of the throat, tongue and lips, or difficulty swallowing. Anaphylactic shock, which occurs in the most severe cases, can lead to dizziness, blackout, and cardiac arrest if not treated right away. Your allergic reaction will be treated with epinephrine, antihistamines or steroids at the hospital to stabilize your symptoms. If you know yourself to be allergic to fire ant stings, you might already be carrying an epinephrine shot, commonly called an epi-pen (epinephrine). Inject yourself or have a friend help you, then proceed to the hospital.
