My doctor is aware of my low blood pressure too. She said some people just have it, can't explain it.
I know when I feel faint I tingle. I'll be walking with my husband in the store and I'll grab his arm. I say wait, I feel faint. We stop, it passes and we go on about our business.
I've come to accept it because it's not everyday, I don't have to be sitting and get up quick to experience the rush. It happens out of the blue.
I've never passed out. Well only when I was on flomax. It couldn't be helped. It says on the prescription it can cause dizziness and fainting. When I'm on that, I get up slowly.
I also have an enzyme in my blood that causes my blood to clot faster than most people. I am considered an excellent blood donor. Only thing, the few times I donated, I couldn't drive home. I felt super faint.
This all started when I was very young. If I had something, I'd assume by now I'd be dead.
