Hi there. BP is really funny. it often goes up a lot just by you deciding to take it. even though you may feel chilled, it must be sub consciously being forced up or something?
What you really need is a 24 hour ABPM test. make sure to get one. Its a continuous 24 hour bp monitor. it takes about 40 bp measurements during the time. The first couple of readings are discarded and about 20 hours are used to gauge average daily 24 hour bp.
This is where you need to start.
My own bp could be 150 + on starting, but after an hour its less than 120!, so the white coat effect is something thats very very real.
See how the 24 hour goes, only then can you make a full observation on you real bp.
I get very nervous when taking my BP, so much that it runs the systolic way up....then after the initial pounding, and pulse increase, the second reading is way lowere..but overall, the best answer I can give, is that BP varies anyway, and when a person suffers from anxiety or panic disorders, man you can really drive up your BP...
and when people say relax, THAT IS EASIER SAID THAN DONE....I have often thought, if a person could relax, don't you think they would.....your GP will know what (if anything) to give you.....I am currently on several different meds for HBP and CAD and anxiety.....meds are supposed to help you....so good luck.
