These injuries often affect the fingers, toes, nose, and ears since they are less commonly covered by clothing when in cold environments. [1] 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]
Pernio or chilblains are inflammation of the skin from exposure to wet, cold (non-freezing) conditions. They can appear as various types of ulcers and blisters. [10] Bullous pemphigoid is a condition that causes itchy blisters over the body that can mimic frostbite. [18] It does not require exposure to cold to develop.
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.

As defined, acute inflammation is an immunovascular response to inflammatory stimuli, which can include infection or trauma. [24] [25] This means acute inflammation can be broadly divided into a vascular phase that occurs first, followed by a cellular phase involving immune cells (more specifically myeloid granulocytes in the acute setting). [24]
Diabetics have a 15% higher risk for amputation than the general population [2] due to chronic ulcers. Diabetes causes neuropathy, which inhibits nociception and the perception of pain. [2] Thus patients may not initially notice small wounds to legs and feet, and may therefore fail to prevent infection or repeated injury. [8]
Bacterial infections, like staph. The bacteria staphylococcus aureus (staph) always exists on the skin’s surface, but can create problems when it enters the body through a cut or wound.
