from the avg of 120/80, my blood pressure was 120/100. I dont know why I have high bp, it doesnt run in the family, and i eat healthy. the only thing that was different was i had it checked the day after i came back from a 15 hour ride on the plane, therefore i got practically no sleep. also even before i was on the plane, i only slept about 3-6 hrs on avg, and i dont know why. however after i came back i slept for a good 12 hrs, and then i went to the doctors. i was also nervous and uncomfortable in the room. so is that why i have high bp, or just because i do? p.s- i can feel my heart beating most of the time, it keeps me distracted and worried.
