Frostbite looks a lot like a burn. There's a similar redness and swelling as well as blistering. It has certainly been cold enough around my house for frostbitten toes and I'm sure several of my readers are in the same boat.
Do you know what frostbite looks like?
Here are some frostbite pictures to help you decide whether you should be going to the doctor. These aren't definitive and I'm not giving you medical advice, but if you think you might have frozen a toe or a nose, it's a good idea to have a medical professional take a look.
