Warm up the right way. If you become frostbitten, don't run to the nearest radiator, hot stove, or roaring fire. Ironically, you could end up burning yourself, since you may not be able to feel intense heat with frostbitten skin. For the same reason, do not use a heat lamp, hot-water bottle, or heating pad to warm up. Submerging the affected extremity in a sink or basin full of warm water (104 to no more than 110 degrees Fahrenheit) is the safest way to treat the frostbite. Once your fingers or toes are warmed up, very gently wiggle them to increase the circulation to the area. You can usually warm up frostbitten ears or a frostbitten nose simply by coming in from the cold to a warm room. If not, gently apply warm compresses to the affected area. Do not rub the delicate tissue.

I would use some aloe vera gel if you have any
to soothe your skin.

Hope you feel better soon~!!
