Chilblains are usually treated at home with lotions and medications, according to Mayo Clinic. Chiliblains show up as red, itchy swellings on the patient's skin and usually go away over time.
As the weather warms up, chilblains may get better on their own, according to Mayo Clinic. They usually clear up within one to three weeks but may continue to occur seasonally for years. Chilblains do not usually cause permanent damage, but if they are untreated, they can lead to infection. The best ways to avoid getting chilblains are to avoid exposure to the cold, dress warmly and cover exposed skin.
