In severe cases blistering, pustules, scabs and ulceration can occur. Occasionally the lesions may be ring-shaped. They may become thickened and persist for months. In children recurrences each winter for a few years are common but complete recovery is usual. Chilblains in elderly people have a tendency to get worse every year unless precipitating factors are avoided.
Treatment Unfortunately chilblains respond poorly to treatment.
Antibiotic ointment or oral antibiotics may be necessary for secondary infection. The hands and feet must not be allowed to get cold. Take vasodilator medication such as nifedipine prescribed before the onset of cold weather and taken throughout winter. Side effects include flushing and headache.
