Doctor's Notes on Frostbite
Frostbite refers to severe damage to tissues that is caused by prolonged exposure to extremely cold temperatures. It results from the formation of ice crystals within cells, rupturing the cells and leading to cell death. There are four stages of frostbite.
Signs and symptoms of frostbite include:
- pain in the affected area,
- numbness,
- burning,
- tingling,
- pale skin, and
- the development of clear blisters.
Associated symptoms of deep frostbite may include:
- complete loss of sensation in the affected area;
- skin changes such as a pale, yellowish, bluish, gray, or mottled skin color;
- blood-filled blisters on the skin; and
- a firm, solid feel to the affected area.
What Is the Treatment for Frostbite?
Treatment for frostbite may include the following:
- Rewarming of the affected body part, usually done gradually with a warm water bath
- Wound cleaning and care
- Medications to control pain
- Antibiotics to prevent or treat infection
- Drugs to destroy blood clots in severe cases
- Surgical removal of damaged tissue, after some time has elapsed
- Amputation in severe cases

Cellulitis
Cellulitis is a bacterial infection of the skin and soft tissues that causes swelling, redness, tenderness and warmth. Treatment will involve antibiotics. Severe infection may require IV or intramuscular antibiotic injections. -
Cold Hands and Feet
When parts of your body get too cold, like your hands, feet, and sometimes other parts of the body, especially your ears and nose, they can be injured or react in different ways. Symptoms and signs of cold hands and feet include loss of sensation, numbness, tingling, itching, burning, unusual color of the affected area, and blistering. Types of cold injury include frostbite, frostnip, immersion, pernio, Raynaud's phenomenon, cryoglobulins, and cold urticaria. The best treatment is rapid rewarming in the emergency department. -
Dehydration in Adults
What are the symptoms of dehydration? Signs include increased thirst, headache, dry skin, dizziness, sleepiness, decreased urine output, dry mouth, and few or no tears. Learn about causes and treatment. -
Dehydration in Children
Dehydration in children can result from not drinking enough liquids, vomiting, diarrhea, or combination of these conditions. Causes of dehydration in children include viral, bacterial, or parasitic infections, diabetes, and increased sweating, and others. Symptoms include sunken eyes, decrease in urination, no tears when crying, dry mouth, lethargy, and irritability. Treatment at home includes proper fluid replacement. Some cases of dehydration are so severe they may require hospitalization. -
Earache (Ear Pain)
Earache is pain in the ear. An earache can be caused by infections or fungus. There are types of ear infections to include otitis externa, otitis externa (swimmer's ear), otitis media, and myringitis. Symptoms of an earache include pain in the ear, fever, fluid seeping from the ear, and headache. Treatment of earache depends on the cause. -
Frostbite vs. Hypothermia Differences in Symptoms and Stages
Frostbite and hypothermia are two real dangers from cold exposure. Aside from cold exposure, risk factors for frostbite and hypothermia is alcohol consumption. Fingers, toes, ears, and nose are the first parts to freeze. Treatment for frost bite and hypothermia includes warming the person.Frostbite occurs when the body is exposed to extremely cold temperatures. For the body to continue functioning under these conditions, blood circulation moves to the internal organs and brain, and away from the skin and extremities, for example, the fingers, hands, toes, and feet. The lack of blood circulation to these body parts causes frostbite. Hypothermia occurs when the body is exposed to extremely cold conditions over a prolonged period, and as a result the body temperature becomes dangerously low (95 F or 35 C). -
Gangrene
Gangrene describes death of body tissue due to reduced blood flow (dry gangrene), infection (wet gangrene), or the bacteria Clostridia (gas gangrene). Symptoms include skin discoloration, fever, pain, swelling, foul odor, numbness, discharge, rapid breathing, and rapid heart rate. Antibiotics and surgery are effective treatments for gangrene. -
Hand Injuries
Hand injuries can be divided into six categories. 1) cuts and lacerations, 2) fractures and dislocations, 3) soft tissue injuries and amputations, 4) infections, 5) burns, and 6) high pressure injuries. Treatment of hand injuries depends on the type of injury. -
How Do You Treat Frostbite on Your Hands?
Frostbite is damage that can happen to skin and other tissues anywhere on the body caused by exposure to cold temperatures. First aid for frostbite on the hands includes moving to a warmer area as soon as possible, removing wet clothing, warming the affected area, immersing the affected body part in warm water, using body heat, and more. -
Hypothermia
Hypothermia occurs when the normal body temperature of 95 F (35 C) or lower. Causes of hypothermia include exposure to a very cold or frigid environment (primary hypothermia), or when the body's temperature is altered by disease (secondary hypothermia). Treatment of hypothermia depends on the length of exposure. -
Raynaud's Syndrome
Raynaud's syndrome (also called Raynaud's phenomenon) is a blood vessel disorder. The smooth muscle in the walls of arteries contract, causing "vasospasms" of the small vessels that supply blood to the extremities. The typical features of include changes in the color of skin from pale to bluish to red, which typically occur after exposure to cold temperatures. The disorder is sometimes referred to as "white fingers disease."
