I went to my doctor about 3 mohths ago for an annual physical. My blood pressure had been about 137/85 the year before, but this year it was 160/90, so she put me on 1 Diovan 80 mg, fsily. I have been having a lot of stress lately, so I checked my blood pressure at a machine at Sam's Club. It was 185/78. I decided to purchase a arm cuff blood pressure monitor. I did that two days ago. I have been taking my reading 3-4 times a day. Yesterday, my readings were 145/63, 179/67 and 161.71, Today, I have taken my blood pressure 3 times. The readings have been 175/83 at 9:30am, 180/76 at 1:00pm and 184/78 at 7:pm. Should I be calling my doctor tomorrow and tell her about this and see if my blood pressure medicine should be adjusted, etc.? How dangerous is it to have your blood pressure over 185 or so?
