The diagnosis of Flammer syndrome is primarily based on the patient's history with its typical features as well as the findings of nail fold capillaroscopy. This test shows an excessive constriction (narrowing) in the smallest blood vessels (capillaries) of the fingers in response to being exposed to cold.
Chilblains of the feet, caused by excessive exposure to cold and humidity. The areas most affected are the toes, fingers, earlobes, nose.
