You got great info from Tick Tock and Huntress.
I'll just add that optimal BP # should be 120/80 or below.
What kind of home monitor are you using? Stay away from wrist and finger monitors. They are notoriously inconsistant and unreliable.
And relax for about five minutes, sitting in a chair, legs uncrossed before you take your reading. Keep your arm very relaxed, resting on a table at about heart level... Don't stiffen or tense it, or you might get an inaccurate reading. Some doctors recommend that you take it three times at each sitting, resting a few minutes in between. Throw out the first #, then average the last two. And make THAT one the one you record on paper.
And take your BP at the same times every day. Note also, that for most (but not all) people, BP is highest upon arising in the AM.
If you continue to get 162/102 for the next two days, call your doctor.... That's not borderline and you should get his input....When does he want to see you again?
And lastly, you said "numerous" times a day...Don't go crazy with this. Three or four times a day is really sufficient to get a good idea of how you're doing. Sometimes, when we get obsessed with all this monitoring, it creates much more anxiety and hence, higher #s!
