What Are The Symptoms Of Bundled Nerves?

My friend s family has a strange genetic condition where their hands and feet hurt when they become sick. They wrap them in frozen wet towels and they start to steam in minutes. Their description of the pain sounds similar to poor circulation like when your hand or foot falls asleep accompanied by the heating aspect. The youngest child has been in and out of the doctor his whole life. They have been testing him the whole time with no results. As they age the symptoms improve and even go away. The doctors they have seen have diagnosed it as bundled nerves. Are there any similar cases on record? All but one of the family have the same condition.
