Hello, A couple of days ago, my blood pressure was 138/83 . . . today, it was148/100. I am experiencing shortness of breath & fatigue. I am a 47 yr old female . . . 5'4" 130 lbs. a non-smoker, and not over-weight, exercise regularly. Can you please explain what could be causing this? I am a bit concerned. Any tips/advise would greatly be appreciated. I was told that my grandfather survived 2 heart attacks before finally dying from his 3rd attack. Thank you! Jen
