Same here, went to the doctor around Feb, for a regular check up, initial 185/100, after being around the 122 range after 2 years on Losartan. Get told I should go to Walgreens, etc where they had a machine that could test it. So I go there after leaving the DR's office. Pharmacist takes me to the room with the machine, and It' gets reading from anywhere from 198 to 226. Pulse rate was around 99-100, Pharmacist having taken this by hand. He's concerned, calls DR's office inquiring if he should call an ambulance for me. Office advises him to tell me to come back cause they will treat me there. So I got back, taken to an empty room where i am told to lay down after taking this pink colored pill, end up taking 3 doses of it until the machine at the office ended up clocking in at around 175/90 I believe.
So doctor advises me to walk in tomorrow and see if there is any changes. Next day, same reading of 185 again. Doc tells me that is the new baseline and gives me samples of Edarbi 80mg, 1 per day. Cool Go home, later on that day I end up suffering a panic attack over the whole ordeal, so I check myself into the hospital initial readings were 175 abouts. End up spending 3 days in there, BP levels rose and fell below that number, but never to 200. lowest was around 118/60 upon waking up during the early mornings due to the cuff filling up. Blood work, Urine sample, x-rays even a CTA, all came back normal. Potassium levels were low, so I was given half a pill for it. One thing that struck during my brief stay there was one of the nurses mentioning a relative's getting high readings when in places like a doctor's office, but low readings when preforming the test at home. So I can't help but wonder if anxiety could play a factor in for the high readings when going to such places.
