My blood pressure is always high when I'm having anxiety and it can get really high! And every time I go to the doctor, it's a little high, like 135/85. After the examination and talk with doctor, it goes down. Be careful when taking your bold pressure at stores (those machines available in some stores), when we are walking, stressed, the reading will be higher. You have to sit and relax for 5 minutes before taking it. Hope it helps!
Everytime i go to the Dr. i sike myself out while they are taking my blood pressure and it is always high. They tell me to relax don't think about it and we will take it again, sure enough it is low. I highly suggest you do what remar said. Relax, don't think about it, and take it. of course your blood pressure was high when you were mad, stressed. this is going to happen to everybody.
Mine always goes high when I'm stressed or scared in think its naturel. But stress is bad for you try not to think about it as much. Your headaches could be do to the stress I get them sometimes when I'm having bad day.
You need to sit quietly for about 5 minutes before taking your blood pressure. This will give you a true reading. If you're upset or have just sat down to take it you won't get a true reading.
If you keep getting high readings at home get in to see your Dr. to find out if this is indeed high blood pressure or stress and anxiety.
