I don't know what to do about it either. I have the same problem when I see my doctor also. At home - my BP is pretty good - but when I am at his office or at the hospital for any tests - I get High blood pressure. I know it has to do with my past experiences with those doctors (bad) - and it is psychological - but I can't seem to get past it.
* I recall only one time - I had made a 9 oz bottle tea with turmeric, cumin, and Celery seed and I sipped it while I waited for my appointment and it came out to be around 100/60 - but I haven't done that lately. I just forget to do it.
Good luck to you!
Share if you find something natural to do or take before seeing the doctors. I'd be interested. You might want to try the tea I said - it is kind of a strange taste - but it is better than the stuff they want to give you!
