I'm only 24 and I have been having pressure (a feeling of blood rushing to my head) when I look up and down. I also get a sensation of my heart pounding. I do not have high blood pressure. It is quite low because I am very thin.

I went to the ER two years back and they said that when I stood up that night and they took my heart beat count - it went up forty beats when I stood. The beat when standing went back to normal after iv fluids. I have had all kinds of heart tests though. Stress test, holter 2 week, holter 2r hour, echo, ekg last year. The works. Should I be worried guys? I have not been drinking much lately.

I also get a mild numb sensataion in my left arm from time to time and a few weeks back my pinky toe went white and completely numb for ten minutes. Could it be my circulation? How do you help that?

Thanks so much guys! I've been super worried about this because I have three little ones to care for. They need Mommy!
