Continue rewarming for 15-30 minutes until distal tips are flushed and soft. Severe pain during the process indicates nerve viability.
Never massage, rub with snow, or apply dry heat (heating pads). These actions cause mechanical trauma, worsen vasoconstriction, or create thermal burns on insensate skin.
