What you need to know about
When exposed to cold temperatures or under stress, several parts of your body, including your fingers and toes, become numb and chilly. Smaller arteries that provide blood to your skin narrow due to Raynaud disease, reducing blood flow to the affected areas (vasospasm).
Raynaud disease, sometimes referred to as Raynaud’s or Raynaud’s phenomenon or syndrome, affects more women than males. People who live in colder climates seem to experience it more frequently.
The severity of Raynaud’s disease and any coexisting medical issues will determine how you are treated. Raynaud’s disease generally doesn’t cause permanent disability, but it can lower your quality of life.
