6yr old son gets hot swollen hands, fingers, ears, lips in cold weather or extremely cold food, depending on exposure. What causes "hot swollen skin"?

1 doctor answer
Dr. Joseph Bouvier
24 years experience in Pediatrics
See below: Increased blood flow to theses "extremity areas" is likely the cause. As long as there is no pain, this is natural (to an extent) so to keep these areas from loosing blood flow (cold can do this) and thus decreasing oxygen to the tissues, where, if without, tissues metabolism slows and if it stops, tissues can die. His response may be slightly exaggerated but, without pain, i would not worry.
