Does anybody have any understanding of blood pressure? I need to go to my surgery to add my BP to my records before they will repeat my HRT prescription and I checked it yesterday as a family member has a BP reader. It is 131/84. Family member (elderly) said that is very normal/good, but Dr Google seems to think it is on the edge of not so good - I'm wondering if it was a one off and I should go to the surgery, or is it a fine BP to submit by email? Thank you! (I'm early 50s and generally fit and healthy).
