Patients with early recovery of sensation in the affected part, blisters filled
with clear fluid, and healthy-appearing skin color have a better prognosis
for full recovery than those whose skin has turned bluish, has blood-filled
blisters, and looks frozen.
People who have recovered from frostbite have an increased risk of
another episode during future exposures to cold. They should take extra
precautions to dress properly for extreme cold or avoid it altogether.
They may also notice that the frostbitten parts of their body are more
sensitive to ordinary cold weather, and ache or tingle whenever they are
outdoors.
About 65 percent of people with severe frostbite will eventually
develop arthritis in the affected hand, foot, or leg.
