Hello,
I am 74 and suddenly my face, neck, ears will redden and look/feel hot/warm to the touch. No emotions cause this. It may last half hour. No pain nor symptoms elsewhere, no dizziness; BP taken after episode is normal. No pains in chest or elsewhere. In morning shower with water running warm over head, I have noticed my facial cheeks are cold - odd? Also, I seem to feel cold when others around me state the air is warm (in a room). This has been going on for over a year. Wife is concerned.
