How is frostbite diagnosed?

Frostbite is typically diagnosed through physical examination and interviews. Understanding recent exposure to extreme cold usually makes the diagnosis clear. MRI can be used to assess the extent of tissue damage to the exposed area.

A doctor usually diagnoses frostbite by looking at your skin. Numbness, skin discoloration, and blisters may indicate the diagnosis if the patient has also been in cold temperatures. Doctors may do tests, such as an MRI, to determine the extent of the tissue damage.
