White coat syndrome as others have mentioned. I have this problem too (inherited from both sides of my family) and not a single doctor that I've seen pays attention when I tell them. Every year or so I spend a day or two testing myself at home and get normal readings but to them all that matters is the high systolic reading in the office. For some reason they find it inconceivable that an injured person who's in a building full of sick and dying people would exhibit an obvious symptom of stress like transient elevation of blood pressure ¯\_(ツ)_/¯
