When I wake up in the morning and especially this morning, I felt very anxious and weird. I took my blood pressure which was elevated. I didn't like the reading so therefore I took it again and the numbers were a bit lower. And then I took it again, and the numbers lowered a bit again. Why does this happen. Which numbers should I consider relatively correct numbers. I'd like to consider the lowest one but in actuality, is it the very first reading that is more accurate? So confused. Thanks for your responses.
