(HealthDay News) -- A food allergy -- commonly to edibles such as shellfish, nuts, wheat, eggs or milk -- often has telltale warning signs.
The American Academy of Allergy Asthma and Immunology offers this list of possibilities:
- Skin that itches, turns red or develops a rash.
- Watering, tearing eyes that may also itch.
- Itching or congestion of the nose.
- Diarrhea, abdominal pain, cramping or vomiting.
- Swelling.
Difficulty breathing, wheezing, chest tightness, tingling of the extremities, or constriction of the throat indicate a serious allergic reaction that requires immediate medical attention.
