frost nip the first stage of frost bite can happen at just below freezing, in minutes. some folks w circulation issues are very prone. pain is primary clue, along with color changes to skin.
if not too bad, submersion of affected body parts in warm water maybe sufficient. if blisters have occurred, get emergency care.
refreezing after warming is esp dangerous.
be extra careful of kids and pets out there.
take care
