Hi, may I answer your health queries right now ? Please type your query here... My blood pressure has been high all day, but it has really spiked since I started laying down to go to sleep. It has gotten up to 193/118, but then once I am up for a while, it drops. The last reading was 160/100, but now my machine is giving me an error reading. My wife happens to take HCTZ. I am wondering if I should go the ER, take one of her pills, wait it out, etc.
