In most cases, the cause of Raynaud's isn't known. This type of Raynaud's is called Raynaud's disease or primary Raynaud's.
Sometimes a disease, condition, or other factor causes Raynaud's. This type of Raynaud's is called Raynaud's phenomenon or secondary Raynaud's.
Causes of Secondary Raynaud's
A number of different things can cause secondary Raynaud's, such as:
  • Diseases and conditions that directly damage the arteries or damage the nerves that control the arteries in the hands and feet
  • Repetitive actions that damage the nerves that control the arteries in the hands and feet
  • Injuries to the hands and feet
  • Exposure to certain chemicals
  • Medicines that narrow the arteries or affect blood pressure
