More than 90 over 60 (90/60) and less than 120 over 80 (120/80): Your blood pressure reading is ideal and healthy

More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it

140 over 90 (140/90) or higher (over a number of weeks): You may have high blood pressure see your doctor or nurse

this is basic guidelines from NHS but only one of your readings raises worries

was the nurse who took reading worried

things that may help lower it
keep stress to min
eat less salt
eat more fruit
drink less booze

the test/tren of course could well be the cause
but have no advice really for you but keep eye on it
