What It Is

Raynaud's Phenomenon causes colour changes in the fingers and toes after being exposed to cold or going through an emotional event such as stress or anxiety (NHS, 2023). The colour changes happen because the small blood vessels narrow (spasm), which reduces the blood supply to the local tissues. Initially, the affected finger or toe turns pale or white due to the lack of blood. It then turns blue and feels cold and numb, as the blood left in the tissue loses its oxygen. As you warm up and the blood flow returns, the area turns red and may tingle, throb or swell (NIAMS, 2024a). Some people also find that their ears, nose or lips are affected (NHS, 2023).

Who is Likely to Get Raynaud's?

  • Women are more likely than men (NIAMS, 2024a).
  • The primary form (where there is no known cause) usually starts before the age of 30, often in the teenage years (NIAMS, 2024a).
  • The secondary form (linked to another health problem) can occur later in life.
  • The secondary form is mainly linked to autoimmune and connective tissue diseases, certain medicines, and work exposures such as using vibrating machinery or handling cold or certain chemicals (NIAMS, 2024a).
  • People with rheumatoid arthritis, lupus, scleroderma or other connective tissue diseases are more likely to have the secondary form (NIAMS, 2024a).

The cause of primary Raynaud's is unknown. The secondary form can be caused by autoimmune disorders, as well as trauma/injury such as previous frostbite (NIAMS, 2024a). Stress can also bring on attacks, due to the autonomic nervous system (the nervous system that causes the blood vessels to narrow and widen). So relaxing and coping with stress can be one of the best strategies to reduce symptoms (NIAMS, 2024b). If you suspect you have Raynaud's the best person to see would be your doctor.
