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. Raynaud's syndrome can be a primary condition, with no known cause, or secondary to other underlying conditions, such as autoimmune disorders or occupational exposure to vibrating tools.
