Understanding Allergies -- Symptoms

What Are the Symptoms of Allergies?

 The symptoms of allergies include:

  • Sneezing, nasal congestion, and coughing
  • Wheezing
  • Itchy eyes, mouth, and throat
  • Stomachache, frequent indigestion, and heartburn
  • Irritated, itchy, reddening, or swelling skin
  • Stiffness, pain, and swelling of joints

Call Your Doctor About Allergies if:

  • You have violent stomach cramps, vomiting, bloating, or diarrhea; this could point to a serious food or other allergic reaction or food poisoning.

Get immediate emergency medical treatment if:

  • Swallowing or breathing becomes difficult or painful; you may be experiencing an asthma episode, anaphylaxis, or a heart attack.
  • You suddenly develop skin welts accompanied by intense flushing and itching; your heart may also be beating rapidly. These symptoms may indicate the onset of anaphylactic shock, an extremely serious allergic reaction.
