Chronic Spontaneous Urticaria

Chronic Spontaneous Urticaria (CSU) is a condition where the skin develops itchy, red, and swollen welts or hives repeatedly for six weeks or longer, without an apparent trigger. It occurs when the immune system mistakenly releases histamine and other chemicals, causing inflammation and swelling in the skin. The exact cause is often unknown, but factors like stress, infections, or allergies can play a role. CSU can affect daily life due to persistent discomfort, but it usually isn't dangerous. Treatment typically involves antihistamines and lifestyle adjustments to manage symptoms.
