I have always had normal blood pressure in the range of 112-120/65-70.
I hadn't checked it in a few months and all of a sudden it has been in
the range of 136-149/85-90. I'm a bit concerned as to the reason for
this. I've been feeling fine. Does anyone have some ideas as to why
this might be. I've always been very healthy my whole life. I am a 54
yr. old female.
Many things can cause your blood pressure to temporarily rise. If it is still worrying you, your best bet would be to set up an appointment with your doctor and have them give you some tests to discover what may have caused the rise in pressure.
I hope that was helpful sorry about the delay
