Wheals

Wheals are raised, itchy welts on the skin, often red or pale, that are typically caused by an allergic reaction, insect bites, or other irritants. They are a type of skin rash characterized by localized swelling. The wheals develop quickly and can disappear within hours or days. They are a common symptom of conditions like hives (urticaria) or angioedema. Their appearance can vary in size and shape, and they may itch intensely. The underlying cause often needs to be identified to manage and treat the condition effectively, sometimes with antihistamines or other medications.
