Health Tip: Have a Food Allergy?

(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.
