Raynaud’s syndrome: 

Raynaud's syndrome, also known as Raynaud's phenomenon or Raynaud's disease, is a condition in which the blood vessels in the fingers and toes constrict, causing a decrease in blood flow to these areas. This results in color changes, usually to white or blue, in the affected fingers or toes, as well as pain, numbness, and tingling.
