What are the symptoms of Raynaud's phenomenon?
If you have Raynaud's phenomenon, you may experience the following:
- fingers, and sometimes toes, change colour (white to blue, then red) when exposed to cold conditions
- pain, tingling and numbness in the fingers or toes
These attacks often only last a few minutes, and you may find that moving into a warmer environment often stops the attack. With primary Raynaud’s phenomenon your fingers go back to normal after each attack.
Attacks can be a nuisance and can cause you a lot of discomfort, but if you have primary Raynaud’s phenomenon they won't damage your fingers.
Secondary Raynaud’s phenomenon can be more severe and may rarely cause:
- open sores (ulcers) on the fingers
- loss of circulation and tissue at the fingertips (referred to as gangrene).
