This passage discusses the various triggers for Urticaria and Angioedema, including perfume, dust mites, hairspray, nuts, solvents, tight clothing, pressure, cheese, and dogs. The author attributes these reactions to a hyperactive immune system rather than traditional allergies. Dr. Gary's research suggests that Urticaria patients don't experience allergies, but rather their immune system becomes hyperactive when exposed to certain stimuli. The recurrent nature of hives is described as a draining and disheartening condition, causing constant itching, pain, and redness. The text emphasizes the impact on daily life, disrupting focus and vivacity, making it difficult to engage in favorite activities. Idiopathic Urticaria is acknowledged as not inherently destructive, but the persistent discomfort can be exhausting, leading to restlessness and discouragement.
