When the temperature starts to drop and the snow starts to fall, while it may be beautiful, you need to be careful when going outside.

Frostbite and hypothermia are extremely dangerous and can cost you limbs, such as fingers or toes, or worse it can be fatal.

With frostbite, the early symptoms may be simple, such as redness or a burning sensation in the fingers..

However, if you start to develop later symptoms it could be too late.

"More severe frostbite your fingertips turn white or pale, they go numb, blisters can form, said A.T. Still University Kirksville Family Medicine Internal Medicine Specialist Velena Fiscus, D.O. "When you get to the later stages of frostbite those are not reversible and people can lose fingers and toes when it gets to those stages and the skin can turn dark, dusky, purplish or black and that's usually too late for treatments."

That's why doctors say if you start to feel any symptoms, go inside immediately.

"When you start to notice your fingers starting to get red or stingy you need to stop, go inside get warm and put on more protection to your hands," Fiscus said

Hypothermia can potentially be even more dangerous if not treated right away.

The symptoms aren't as obvious, with one of the earlier signs being you actually start to warm up.

"Some people start to get hot and take off their clothes because they're feeling too hot and they can have confusion, sometimes dizziness, their hands can be really cold and their feet can be really cold, so those are earlier symptoms," Fiscus said.

Some of the later signs include increased confusion and a lack of awareness of what is going on around you.

If you start to have any of those symptoms you need to get inside immediately.

"Stop what you're doing, get inside and warm yourself up," Fiscus said. "If you're at a place where you can't get inside the house go into your car, start your car, run it, sit on your hands, get them warm (and) If you have blankets in your car make sure you cover-up."

If you are where you can't get inside quickly, call a friend or 911 so they can come and help get you to safety.
