What Is Frostbite?

To refer a frostbite patient or if you are concerned about your own frostbite injury, please call:


A burn charge nurse answers this number 24-hours a day.

Frostnip is mild frostbite. It may cause numbness and pale skin to the affected area, however, it is not a deep injury.

Frostbite is a traumatic injury where the skin and sometimes tissue under the skin freezes. Frostbite injury can occur to fingers, toes, ears, and nose.

Frostbite can also lead to long-term disability if  you don’t get treatment. Specialists at University of Utah Health's Burn Center provide expert care in frostbite treatment and management.

What Causes Frostbite?

You can get frostbite if your skin is unprotected and exposed to cold temperatures. You can get frostbite even if you are wearing gloves or other clothing to protect your skin.

Signs of Frostbite

Frostbite is similar to a burn injury, only caused by cold rather than heat. The first signs of frostbite are:

  • cold skin and a prickling feeling;
  • reddened skin that turns white or pale;
  • numbness in your nose, chin, ears, fingers, or other area; and
  • stinging, burning, or swelling.

These first signs are called first degree frostbite injury.

Second degree frostbite is when you see light colored blisters and your skin starts sloughing or shedding. Blood filled blisters are signs of third-degree frostbite. These may occur after you have rewarmed your skin.

The worst type of frostbite, fourth degree, is when bone, tendon, or muscle has frozen.

When You Should Go to Urgent Care or an Emergency Room

If you have any of the following symptoms, you should go to urgent care or the ER:

  • Loss of feeling or sensation to frostbitten area
  • Increased swelling, redness, or pain to frostbitten area
  • Symptoms of hypothermia: shivering, confusion, slurred speech, drowsiness
  • Fever or other signs of infection

Frostbite Treatment

When you are treated for frostbite, the first priority of your treatment team is to stop the injury from progressing. This initial treatment plan may include rewarming.


In the rewarming process, we will warm up the area that has been damaged. We will slowly dip the area in warm water. Sometimes you may need medications to help relieve the pain. It is important that your care team monitors this process

Other Treatments

You may need additional treatments. These could include any of the following: 

  • Surgery—Depending on how severe the frostbite is, you may need surgery.
  • Wound care—Wound care is the process of preventing infection. This includes washing and bandaging your wounds.
  • Pain control—Your comfort is a top priority for our treatment teams. We will give you pain medications as you need them.
  • Intravenous fluids for hydration—We may give you an IV to make sure you get enough fluids and don't get dehydrated.
  • Treatment to promote circulation—Rewarming the injured area will help with circulation. We may also give you medication to improve blood flow to the injured area.
  • Electrolyte replacement—We will make sure you have the nutrition that you need. This may include the replacement of vitamins and minerals.
  • Glucose management—We will monitor your blood sugar. This is another way for us to be sure you are getting adequate nutrition. 

Preventing Infection

Our team will also work to prevent your injury or wound from getting infected. To do this we will:

  • Wash our hands or use hand sanitizer when we enter and leave your room.
  • Wear PPE (personal protective equipment), such as gowns, gloves, and masks.
  • Limit the number of your visitors.
