About these articles

Written From The Exam Room.

Our founder spent more than thirty years in private allergy practice before starting AllergyEasy.These pieces began as his blog and have been updated and consolidated. Each one ends the same way, because the question underneath most of them is the same: can this allergy be treated, not just managed? Usually, yes.Nothing here replaces a conversation with your own physician.

Causes

Usually Allergy. Sometimes Something Else.

Foods, medications, latex, pet dander, pollen and insect stings are the common allergic triggers.Hives and angioedema can also accompany thyroid disease, lupus and other immune disorders, and rarely some cancers. A hereditary form of angioedema stems from a missing blood protein and needs its own treatment. Chronic or recurring cases deserve a workup rather than another antihistamine.Cold urticaria, hives from cold air or water, is an uncommon but real variant.
