Urticaria Uncovered: Understanding The Condition And Optimizing Its Management
Abstract: Urticaria, also known as hives, is a skin condition characterized by pale red, raised, and itchy bumps. The name "urticaria" is derived from the Latin words "urtica" and "urere," which mean nettle and to burn, respectively. This skin rash manifests as pink to flesh-colored plaques that are non-pitting and edematous. The primary cause of urticaria is believed to be a condition known as "Fasad e Dam," which refers to blood …
