Re: What if my blood pressure is 145/88. Is that too high?
If it's falling from that level you don't have much to worry about. Even consistent bp of 145/88 is not necessarily too high, depending on your age.
If your relatively young then, yes, it's a bit worrying. But if you're 60 it's not too bad.
Like Michael says, take readings over a length of time and get a better idea of what's happening. But maybe you've done that already if you know that it's falling. Best wishes that it will continue that way!
