Frostbite is the medical condition where damage is caused to skin and tissues due to extreme cold. It is related to, but not identical to hypothermia. Risk factors include using beta-blockers, and having conditions such as diabetes and peripheral neuropathy.
Generally, frostbite is accompanied with discoloration of the skin, along with burning and/or tingling sensations, partial or complete numbness, and possibly intense pain. If the nerves and blood vessels have been severely damaged, gangrene may follow, and amputation may eventually be required.Symptoms
