Also known as: vasospasm · vascular spasm · arterial spasm · cramping vascular constriction · Raynaud's phenomenon · Raynaud's syndrome · white fingers in the cold · vessel contraction · circulatory disruption caused by spasm
Your Body Is Speaking
Your blood vessels are contracting. Without warning, the fine arteries go into spasm — especially in the fingers, sometimes in the toes, occasionally elsewhere. The skin turns pale, then bluish, then cold. It hurts. Blood flow stalls, as if your body has decided to cut certain regions off from supply. In Raynaud's syndrome, the most well-known form, the fingers become numb, colourless appendages — as if they no longer belong to you.
