J.Griff, I can verify that anxiety can cause BP to rise, sometimes to critical levels because it's happened to me several times in the past year. I am on BP medication anyway but anxiety breaks through that. I have learned that taking slow, deep breaths can bring BP down though. I have white coat syndrome so I monitor my pressure at home and keep a log. Then, when I have a doctor's app't, I bring both my readings and my BP kit with me. I take my own reading after the nurse takes it and my own kit will also show it's elevated, yet at home with the same kit, my pressure is normal, even lower than normal.
Also, make sure when your pressure is being taken that your back is supported (against the wall or a chair back), your feet are flat on the floor and ankles not crossed and your sleeves are rolled up (but not constricting).
Other factors can make false high readings: having just eaten and exercising within maybe half an hour. But for me it's nerves and anxiety. Sorry you're also experiencing it but it's not uncommon. Honest!
