An “attack” usually hits the fingers and toes, but can also strike your nose, ears, nipples, or lips. It might start in one finger or toe and move on to others. It may last less than a minute, or go on for hours. Affected areas might:
- Turn pale, white or even blue in color
- Feel numb, cold, or painful
- Throb, burn, tingle, and swell when blood returns
Serious cases of secondary Raynaud’s can cause sores. Rarely, they can even kill living tissue (gangrene).
