Cold urticaria is a rare condition characterized by the development of hives or welts on the skin after exposure to cold temperatures. These hives typically appear within minutes of cold exposure and can cause itching, redness, and swelling. While the exact prevalence of cold urticaria is not well-established, it is estimated to affect approximately 0.05% to 0.1% of the general population.
Although cold urticaria can occur at any age, it is most commonly diagnosed in young adults between the ages of 18 and 25. The condition can be primary, where no underlying cause is identified, or secondary, which may be associated with certain medical conditions or medications. Cold urticaria can significantly impact a person's quality of life, as it can limit their ability to engage in outdoor activities or even perform routine tasks in cold environments.
Diagnosis of cold urticaria is typically made through a thorough medical history, physical examination, and cold stimulation tests. Treatment options include avoiding cold exposure, wearing protective clothing, taking antihistamines, and in severe cases, using medications like corticosteroids or immunosuppressants.
If you suspect you may have cold urticaria, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate management.
