What is "normal" for you? Take your blood pressure during different times of the day and jot the results down for a few days. Do you see a pattern? Does it change when you just walked up a flight of stairs? Did it change when you were stressed or mad? Write down as much as you can to get a base line. Then take the findings to your doctor and talk things over with them. They know much more then a bunch of strangers on the internet. ☺ Good luck to you. (In my own opinion and I am not a doctor but it seems low to me.)
