What is Raynaud’s Disease?  

Raynaud’s Disease, pronounced ‘ray-nose’ is a condition caused by the sympathetic nervous system which causes narrowing of arteries in the fingers, toes and or nose, resulting in reduced blood flow to these areas. This results in change in colour with fingers turning black or white, and then blue or purple. This cascade of colour changes is known as Raynaud’s Phenomenon. Symptoms include feeling cold, numbness, and occasionally pain in the affected areas.
