Can a bottom number of above 90 cause some dizziness and weird headaches sporadically, not constant. I have gotten my blood pressure down to that from walking and watching sodium, thanks :) To the poster: hey I m doing pretty good then, I don t smoke or drink caffeine... For the other poster, I m a mellow personality already...do you think that will help? :)))) Thanks to you both so far.... I drink tons of water, I m not stressed, I have just seen a doctor, but not one that monitors bp only checks it. My previous bp reading was taken a month prior in a drug store and it scared me. It WAS 155/102...that got me walking and watching my sodium. Thanks all :)
