For your own peace of mind, take your home blood pressure monitor with you to the doctor’s office.
It will be a shock that you will very much enjoy when you see numbers on your device that you have never seen before that high. That will be what absolutely confirms to you that your device is correct, it is matching what they have there and their device at the clinic, and when you’re at home you don’t see those numbers.
And that means you don’t need pills.
I bought a brand called oxyline. Cost me $100. It has been tested and ranked at 99% accuracy 99% of the time. Comes with a lifetime guarantee. That’s good enough for me
That was after I handed her a spreadsheet printout for 30 days at home that showed twice a day I was averaging 122/78.

White-coat syndrome is a real thing, but it is a misnomer. It is anxiety that is self-inflicted. I liken it to going into a final exam for which 50% of your grade is dependent on. In the doctor's office you know that there will be a "grade" that determines your doctors recommendation for a more aggressive drug treatment that you probably don't want or might not need.
