What is frostbite?

Frostbite is a condition that occurs when the skin is exposed to extreme cold temperatures or prolonged cold exposure. In its initial stages, both the skin and underlying tissues can freeze, and in severe cases, blood vessels, nerves, and muscles may also freeze. Frostbite is classified into different grades based on its severity:

• Grade 1: Mild, with no permanent damage
• Grade 2: Tissue amputation, nail sequelae
• Grade 3: Bone amputation, function sequelae
• Grade 4: Bone amputation at the limb, systemic involvement, function sequelae

What are the symptoms of frostbite?

Symptoms of frostbite can vary depending on the severity of the condition. Common signs include numbness, cold skin, prickling sensations, changes in skin tone (white, red, bluish-white, or grayish-yellow), severe joint or muscle stiffness, difficulty moving the affected area, blistering after warming (in severe cases), pain around the exposed area, skin turning black after warming (sometimes taking days to present), and swelling, redness, or discharge around the frostbitten area.

 

What causes frostbite?

Frostbite is primarily caused by exposure to cold temperatures. Prolonged exposure to cold environments or extreme cold without protection can lead to frostbite. Even temperatures above freezing can cause frostbite, especially if the skin is wet or exposed to severe wind chills. Direct contact with extremely cold surfaces can also result in immediate freezing of the skin.

 

How is frostbite diagnosed?

Healthcare providers at Laso MD will evaluate the affected area for signs of frostbite and discuss potential causes before making a diagnosis. Additional tests such as X-rays, MRIs, or bone scans may be recommended to assess damage to bones or muscles and determine the severity of the condition.

 

How is frostbite treated?

If home remedies like warming the area and removing wet clothing prove ineffective, Laso MD healthcare practitioners may recommend various frostbite treatment options, including protecting the area with sterile dressings, assisting with rewarming, prescribing medications for frostbite (such as oral pain medications, infection-fighting drugs, or clot-busting medications), physical or whirlpool therapy, wound care, debridement (removal of damaged tissue), or surgery. Hyperbaric oxygen therapy is also being studied as a potential adjunct therapy for improving frostbite symptoms.

 

When to see a doctor for frostbite?

If you suspect you have frostbite, take immediate steps to warm the affected area, remove wet clothing, and cover yourself with a blanket. If rewarming at home is not effective, seek medical attention. Laso MD healthcare practitioners can provide specialized frostbite treatments and prescribe medications tailored to your condition, helping to protect the area from further damage and promoting optimal recovery.
