I have a friend who became lightheaded and dizzy while we were out shopping; she was also very thirsty and almost fainting. I called the store paramedic who took her blood pressure; he was astonished that she had NO pressure reading. He looked really scared but she told him that she had gotten ill like this a few weeks before, and there was no blood pressure reading at that time either.
What can cause a person to have NO blood pressure reading along with dizziness, thirstiness, etc., and yet still be alive? I wouldn't have believed it if I wasn't there with her this time. She says when it happened before, she was taken to the hospital for tests but nothing was found. Thanks
