Releasing histamine: Hives are due to a release of histamine in the skin, commonly due to allergy to foods, medicines, viruses, molds, animals, pollens, etc... Some people release histamine and get hives when exposed to cold temperatures, cold water, sunshine, stressful situations, etc... Other people with hives may have internal medical conditions such as chemical imbalances, intestinal parasites, etc...

Hives: Foods, infections (usually post-viral), autoimmune disease, hormones, medications, lymphomas (very rare).

Perhaps: Contact urticaria is known to occur but hives from dander in the air is less likely. Finding the cause for this very annoying condition is often very frustrating. Testing guided by a good history and evaluation can help.

Why allergists exist: Finding & treating the cause of allergic reactions is the main function of an allergist. A solid understanding of the immune system is required, so that immunology goes hand in hand. Timing, prevalence of various causes, location, description, examination, associated factors, family history and finally testing enables allergists to identify the culprit, if one is present; treatment is pt-centered.

Common question: An allergist is frequently asked to identify the cause of the allergic reaction. Reviewing the symptoms is a good start---cough, wheezing, runny nose, vomiting, diarrhea, rash, itching, eyes puffy, anaphylaxis. There are many triggers of allergic reactions, the most common being pollens, dust, animal dander, foods, medications, insect stings/bites, latex, metals, etc. Finding the cause is key.
