If you feel pain or numbness in her fingers, toes, nose, ears, or any other body part, check for frostnip or frostbite.
Frostnip is like a warning sign for frostbite, and occurs when cold temperatures damage the skin and blood vessels. Frostnip usually affects the face, feet or fingertips and causes numbess and may turn skin white or blue-white.
Frostbite is literally the freezing of the body — from the skin in! Frostbite can make skin feel waxy, frozen, and numb, and can cause blisters. In extreme cases, blood may stop flowing to the area and permanent damage can be done to the nerves, muscles, blood vessels, and even bones. Plus, once an area is frostbitten, it is more susceptible to frostbite in the future.
If you wear mittens rather than gloves, this allows the fingers to keep each other warm, so this would be less likely.
Sometimes you can get that tingling feeling or pain in your fingers or toes when they warm up after being in the cold for a period of time. Or, your fingers, nose or toes turn blue when they are cold or pressed upon. These are warning signs that you could have Raynaud’s.
