Whatever your circumstance, measure your blood pressure at home. Let those measurements, which you will write down over a period of a week, be the number provided to the doctor for him to interpret and use in making a decision on medication. Do not use the measurement in the doctor’s office.
Oh and one other step in this process is to take your blood pressure measuring device into the office and be sure that it reads the same, which will probably be quite high. And it will be higher than you’ve ever seen it before at home.
Those machines never read as accurately as a well trained physician with a sphygnomanometer. Of course you can’t find a an actual by God well trained GP with a geiger couneter.
I have white coat syndrome. My BP is always high in the Dr. office. I always insist they redo it before I leave, which is then usually closer to normal.
