if your blood pressure is high every time you go to the doctor, but you aren't feeling hypertension effects at home, ask them to try the manual cuff and see if it reads lower! this advice brought to you by the fact that i got a new home blood pressure doodad that goes on my wrist instead of my bicep, and doesn't squeeze nearly as hard, and it consistently reads the bottom number as like 30 points lower than the super squeezy cuff does. i don't know if it's a difference in how it reads or detects my vein, or if it's my own reaction to the painful bicep cuff raising my actual bp when i use that one. i just know the device is skewing the data. this seems pretty big so i figured i should pass it along. edit: actually, this morning the new cuff pinched my wrist because i had it at a slightly wrong angle, and it read high. so apparently it's pain raising my bp. which implies that if getting your bp checked hurts, you're maybe going to be reading high.
