10 Causes of Paresthesia
Reviewed: Dr. Gromatzky
Cause #8: Frostbite
Frostbite occurs when there is exposure to low temperatures, causing the skin and tissues to freeze. The earliest symptom is numbness of the skin followed by a white or bluish discoloration. Blistering and swelling may also occur.
The most common affected sites are the hands, feet, and face. Individuals with frostbite may also experience hypothermia or compartment syndrome. Those at risk include homeless individuals, military personnel, and winter sports enthusiasts. Injury occurs due to the blood clots and ice crystals that are in the blood vessels after thawing. Paresthesia may be present during frostbite and thawing.
