Cold urticaria is a condition that directly affects the skin, as defined by the National Center for Advancing Translational Sciences. Diagnosing it relies on specific signs and symptoms, which we explore below, along with the causes and potential treatments.
CAUSE
According to Dr. Demetrios Theodoropoulos, the cause of cold urticaria is unknown.
However, it is the most common form of urticaria, as explained by the National Organization for Rare Disorders. Although cold urticaria is not typically inherited, it has been associated with certain infectious diseases and blood conditions, such as cryoglobulinemia, chronic lymphocytic leukemia, and viral hepatitis. Familial cold urticaria, another form of the condition, has been linked to a specific chromosome.
Chromosomes carry genetic characteristics, and humans have 23 pairs, with the 23rd pair differing between males and females.
SYMPTOMS
Cold urticaria, whether acquired or familial, manifests as abnormal skin reactions to cold. Exposure to cold weather or swimming in cold water can cause redness, welts, itching, and additional symptoms like fever, anxiety, tiredness, and fainting. In acquired cases, the rash develops within 2-5 minutes and lasts 1-2 hours, while familial symptoms take 24-48 hours to appear and can last up to 24-48 hours in severe cases.
