I have the same problem. So I kept a diary of my home readings and took those records to my doctor visits. They included my records in my medical file and ignored the office bp reading. I had to do this because I didn't want to be given medication based on the office reading. When they did that in the beginning, I ended up in ER because bp was too low. When dosage is based on home readings, I'm fine. Take your bp machine with you to the office visit and the nurse can verify it is calibrated correctly. Even though I think I don't worry about it, it is still too high at the doctor's office. But the doctor looks at my diary and says, great numbers!
