yes, this is the tip. we use a digital blood pressure monitor and it's much more accurate if we take the arm close to the heart. here is the one we bought from Ebay http://www.ebay.com/itm/US-Arm-Digi...312?pt=LH_DefaultDomain_0&hash=item566c0edec0 it works great for about 6 month.Forgot to say, if you're checking your own blood pressure then the left arm is the most accurate as closer to the heart.
I'm the same, white coat syndrome, when at home normal blood pressure, pulse rate around 60, at the clinic or doctors blood pressure high pulse Rate over 100 and I even feel ill, I have one of those watches that takes your pulse and waiting to see the doctor it was around 106, as soon as I got back in the car it was back to 60 lol.My readings at home always differ with the doctor's - at GP always higher.
