Chronic Spontaneous Urticaria (CSU)
Chronic hives, also known as Chronic Spontaneous Urticaria, are red, raised, and often itchy welts that appear on the skin without a known trigger. Unlike allergic reactions or infections, CSU can persist for six weeks or longer and may come and go unpredictably. The condition is not life-threatening, but the persistent itch and discomfort can interfere with daily activities, focus, and sleep. While there is no cure, certain treatments can help manage symptoms for those who do not respond to standard antihistamines.
