Hives, medically known as urticaria, are raised, itchy welts on the skin that can vary in size and appear in clusters. They occur when the body releases histamines and other chemicals, often in response to an allergen, causing localized swelling and redness. Hives can be triggered by a variety of factors, including certain foods, medications, insect stings, or stress. They can last for a few hours or may persist for longer periods in chronic cases.
Treatment for hives generally involves identifying and avoiding the trigger, along with the use of antihistamines to alleviate symptoms. In some instances, more severe cases may require corticosteroids or other medications advised by a healthcare provider. While hives are typically not a serious medical condition, they can be uncomfortable and may signal an allergic reaction that requires attention. It's important to consult with a healthcare professional if hives are accompanied by more serious symptoms such as difficulty breathing or swelling of the face and throat.
