When my granddaughter, age 11, gets in the swimming pool, in her backyard slip and slide or anywhere that her hands come into contact with cold water for a prolonged time, she gets white raised places that resemble
blisters but they are not filled with fluid as
blisters are. They seem to dimish as her hands dry and get warm but then will peel where the places have been. Do you know what would cause this or has anyone had similar incidents.
