What symptom is associated with chilblains?

Chilblains, also known as perniosis, are localized reactions to cold exposure, commonly affecting the extremities such as toes and fingers. The symptoms typically include itching and burning sensations in the affected areas, which arise due to the body’s response to the cold, causing an inflammatory reaction in the small blood vessels. This can create discomfort and tenderness in the skin.

The sensation of itching and burning can be quite pronounced as the skin warms up again after exposure to cold temperatures. In contrast, severe blistering typically indicates a different condition, such as frostbite, rather than chilblains. Dry skin flakes can occur for various reasons, including general skin dehydration, but are not characteristic of chilblains. A systemic rash could signal an allergic reaction or other widespread skin conditions, which is not commonly associated with chilblains. Thus, itching and burning sensations are clearly the hallmark symptoms of chilblains, making this the correct choice.
