Dr. Jay Kashkin answered

Specializes in Allergy and Immunology

Physical : Dermographia (skin writing) is the most common cause of hives. Triggered by heat, vibration and pressure (sometimes cold) it is often associated with food, soaps/shampoo, detergent etc. It is occasionally associated with thyroid disease/autoimmunity but mostly its underlying source is unknown. Treatment begins with antihistamines at 1-4x usual dosing.
