I have noticed that when I'm stressed, my bp drops and my pulse goes up. At the doctor's yesterday, my BP was 90/60 and my pulse was 100. When I'm not stressed, my BP is between 100/60 and 110/60. Sometimes my diastolic is 50 but my systolic has never dropped below 90 when I'm stressed. It's low-normal, but I'm wondering if it's normal for it to happen. I had always thought when you're stressed, everything goes up.
