Hi,
I had pressure of 180/105 for several years, my doctor prescribed beta blockers, they caused me to have migrane effects. I then had all sorts of tablets, pressurealways up, but feeling fine. My pressure was eventually controlled by bendo fluoremethiacide,( almost the correct spelling) a small white table. pressure is now always 120/80 when I am active, and a frightening 90/40 when watching the telly for an hour. very dizzy when first moving from armchair, but soon back to normal. My Moyher has high blood pressure when at the doctors, and extremely low pressure when I it take at my house, this is doctor surgery nerves, I am sure, but they keep giving her tablets to lower her pressure, which makes her dizzy, a bit of a catch 22. I am sure my machine is correct, I take the pressure of all the family, and most are within the normal bounds, so do as an earlier person said, get your own machine ( LLoyds the chemist is very cheap and good quality) and take your pressure at home after relaxing for a while.
all the best,
annie.
