Is 128/90 BP bad?

[star13]

Hello,
I am a 31 year old woman. I have suffered for years with chronic migraines/fibromyalgia/sleep disorder.
My Dr. has had me take my BP at home because I usually get very nervous in the doctors office and it tends to be high.
Lately when I am taking it...it averages around 128/90...is this cause for concern? I am very sensitive to meds so it is scary for me to try any new meds. I am not currently on any meds. I eat healthy...all organic, mostly vegetarian beans/rice, etc...no pancakes/cereal/donoughts/french fries/soda, etc.    It is hard for me to exercise more than a small walk a day due to my physical pain from fibromyalgia, but I try to get a daily walk.
My weight has always been around 155lbs (I am 5'6")...except for a short time in my early 20s when I had an eating disorder and was 115lbs. My weight is now between 165-170lbs which I don't feel happy about yet can't seem to lose even though I try. May have some connection to my fibro. symptoms being so severe.
I was just wondering if my BP is something I should worry about? I am worried already and tend to do so which doesn't really help. I tend to get high BP as soon as I see a blood pressure cuff...plus the one I have you have to pump up with one arm and it is really hard for me to pump so I wonder if it raises my BP just pumping it. If I don't know someone is going to take it.....for example, at the dentist office they never took my BP before so I wasn't expecting it and wasn't worried. And the reading there was 117/73!!!!! I even had them give me a copy so I could show my regular Dr.
Anyways...just wanted to ask if I should be worried?
Thanks so much,
C

Good point!.  I thought the variation favored the arm nearest to the heart, but with some look for confirmation I learn the pressure may be slightly higher in the dominant arm and BP  differences are common.  Several studies have been done to determine what is a ‘normal’ variation between right and left arm. In general, any difference of 10 mm Hg or less is considered normal and not a cause for concern.

American Heart Association: "The fact that there are differences in right and left arm readings emphasizes the importance of measuring blood pressure in both arms initially to prevent the misdiagnosis of high blood pressure.  If one arm has higher blood pressure than the other, that arm should be used to determine if you have hypertension".

If you go for a home BP unit, take your blood pressure at the same time each day or the same time for intervals.  A more accurate measurement would be to average the individuals readings. .

many people get anxious at Doctors when they have blood pressure taken which causes a higher reading. Doctors usually take this into account. The reading from you Dentist is absolutely spot on, nothing wrong with it at all. Anxiety does make blood pressure rise in all of us so perhaps it might be with you purchasing an electronic cuff so you can check it yourself from time to time. If your reading is fine, and you go to the Doctors anytime and he/she decides to check it too, you will know it is normal and have no need to feel anxious.
