Information on ONE of THOUSANDS rare diseases:

Raynaud's (ray-NOHZ) disease causes some areas of your body, such as your fingers and toes, to feel numb and cold in response to cold temperatures or stress. In Raynaud's disease, smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas (vasospasm).

Treatment of Raynaud's disease depends on its severity and whether you have other health conditions. For most people, Raynaud's disease isn't disabling, but it can affect your quality of life.

Doctors don't completely understand the cause of Raynaud's attacks, but blood vessels in the hands and feet appear to overreact to cold temperatures or stress.
