I am 45 years old and in the past I have had high blood pressure, lately I have noticed that after I climb stairs, or do very little exercise, I have a shortness of breath, and I have both my arms tingle or go numb. My father has passed away do to his heart, and I have a 51 year old brother that has had a triple bypass. My blood pressure seems to be fine, but I do not know what is going on?
