Cold Urticaria: Symptoms, Causes, And How To Treat Being Allergic To Cold

Signs and Symptoms: The National Organization for Rare Disorders states that in an acquired cold urticaria, the skin has an abnormal reaction to the cold. For example: after exposing your skin to cold weather or swimming in cold water, your skin will usually turn red and develop welts and itching. These symptoms may also be accompanied by a fever, anxiety, tiredness, and even fainting at times. The National Center for Advancing Translational Sciences adds that the rash will develop within 2-5 minutes and can last between 1-2 hours.

The symptoms of familial cold urticaria take time to develop. Usually, it will take between 24-48 hours for the symptoms of familial cold urticarial to appear. In addition, these symptoms can last up to 24 hours, but in more severe cases they can last up to 48 hours.

According to the National Organization for Rare Disorders, there are sub-categories of the acquired cold urticaria; the first being primary cold urticaria. This can occur between 5-30 minutes after exposure to the cold. Usually itching and reddening will occur first, which will then be followed by a burning sensation. Hives will then appear which will last about 30 minutes. The exposed person may also experience headaches, wheezing or palpitations. The second sub-category is reflex cold urticaria. This is a widespread appearance of welts which occur when the body’s temperature drops after exposure to cold applications.
