You did the right thing, getting a home blood pressure testing unit.
My son had a school physical. His blood pressure was high, so they insisted he see a pediatrician.
The pediatrician went right to it and took his blood pressure. It was high, indeed, and he insisted we go to a pediatric cardiologist.
The pediatric cardiologist lashed him to a table, took his blood pressure, listened for blockages in his legs and all over. His blood pressure was now incredibly high, and the cardiologist was debating openly over whether to send him to the emergency room or put him immediately on a high dose of a very strong blood pressure prescription. He was almost certain that there was a blockage that he wasn't finding.
Meanwhile, I had been watching my son's nervousness ratchet higher and higher with each step further into the wonderful world of modern medicine. That's when I took him back and said, "No thank you." The Pediatric Cardiologist actually said that he could not be responsible for my son's safetey if I took him home. I said, "thank you. That's fine." He told me I was being completely irresponsible and endangering my child. I said, "I don't think so at all." I left with my son, shaking my head.
Twenty minutes later we arrived home and I took his blood pressure on my home machine, an AND 767 model (from A&D) which was approved by and checked with my GP's readings. Pressure just slightly above normal. Two hours later: normal.
Why this long story? Well, because all of my stories are long...
No, wait: I had a point...
It's just that we should not take for granted that what we see at a given moment is true for the rest of the time. If you don't know about your blood pressure, find out before simply accepting a prescription.
I have so-called "white coat syndrome," where my blood pressure goes up dramatically at the doctor's. I looked at my son getting more and more nervous, watched his BP go up right along with the level of the specialist he was seeing, and knew what it had to be. He could have been hospitalized and put on high doses of drugs he did not need, drugs which could have had dangerous effects on him. And the doctors were all adamant and in agreement.
If you go to any doctor with any problem, and you believe you know the cause or the diagnosis, and the doctor doesn't listen or give you any good reason why you can't be correct, be careful about what you let him give you. You can be worse off with the wrong thing. I just have to wonder how many people have prescriptions given or dosages raised because they were nervous, rather than increasingly hypertensive.
All that said, if you find that you do need blood pressure medication, then by all means, get it.
Best wishes,
