"nettle rash"的定义和意义

What is "nettle rash"?

Nettle rash, also known as hives or urticaria, is a skin condition characterized by red, raised, and itchy welts on the skin. These welts can vary in size and shape and may come and go quickly. Nettle rash is often caused by an allergic reaction to certain foods, medications, insect stings, or environmental factors such as pollen. In some cases, stress or infections can also trigger hives. While nettle rash can be uncomfortable and bothersome, it is usually not serious and can be treated with antihistamines to relieve itching and inflammation. In severe cases, medicines that help reduce swelling and discomfort may be prescribed. It is important to identify and avoid triggers to prevent recurring episodes of nettle rash.
