It has been reported that some patients have been misdiagnosed with Acrocyanosis, when in fact the correct diagnosis in their specific case was Raynaud's Phenomenon.
Raynaud’s disease causes areas of your body such as your fingers and toes to feel numb and cold in response to cold temperatures or stress. This is due to the small arteries that supply blood to these areas constricts and slows down blood flow to the affected areas. Symptoms of Raynaud’s disease include cold finger or toes, colour changes in the skin in response to cold or stress and a numb prickly feeling pain upon warming up or when relieved of stress. It can be misdiagnosed as other circulatory syndromes such as peripheral vascular disease, thromboangiitis obliterans, vasculitis or thromboembolic disease.
