In fourth degree frostbite, structures below the skin are involved like muscles, tendon, and bone. Early symptoms include a colorless appearance of the skin, a hard texture, and painless rewarming. Later, the skin becomes black and mummified. The amount of permanent damage can take one month or more to determine.
Affected skin becomes numb, turns white or blue, and develops blisters. [1] Frostnip is a superficial skin injury that won't freeze the skin or cause long-term damage. [8] Frostbite involves freezing of fluids inside and outside of cells that results in cell breakdown, electrolyte imbalances, and inflammation. [8]
Frostbite is dangerous and can often happen quickly, depending on both the temperature and wind chill factor. Here’s how to know if it’s frostbite and how to treat it.
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
Just as heat stroke has the first stage of heat exhaustion, frostbite has a first stage called "frostnip," which occurs when skin is exposed to the cold, usually when temperatures are.
Non-freezing cold injuries (NFCI) is a class of tissue damage caused by sustained exposure to low temperature without actual freezing. [1] There are several forms of NFCI, and the common names may refer to the circumstances in which they commonly occur or were first described, such as trench foot, which was named after its association with trench warfare.
With North Texas temperatures below freezing and wind chill in the 10s, here’s what to know about prolonged cold exposure.
The briefest electric shock type of paresthesia can be caused by tweaking the ulnar nerve near the elbow; this phenomenon is colloquially known as bumping one's "funny bone". Similar brief shocks can be experienced when any other nerve is tweaked (e.g. a pinched neck nerve may cause a brief shock-like paresthesia toward the scalp).
