The symptoms you describe can not be related to a known disorder. The lack of pain also indicates that the condition was within normal physiological changes. Perhaps what you noticed was the appearance of a local vaso-constriction of the outgoing veins due to the low temperature. After such an occurence, vaso-dilatation of the capillaries may have followed. The official medical term for this is " the exhausted local blood vessel constriction reflex" and is quite normal.
