question: Hi my father has these episodes that have been happening once in a while. He says when he feels it coming on he starts to feel hot. Then his face gets really red and he feels like his head is about to explode. He gets shortness of breath and today he felt tingling in his hands and his face swole and his lips swole really bad to the point where he was hard to understand when he was talking after. Also I d like to mention that he is diabetic. Thanks
