I've been having heart palpitations, and it sometimes hurts when my heart beats. I have this ringing in my ears, I've had it for a couple of years, though. Sometimes the hearing will go out in my ears and its only ringing. And lately I've been so dizzy, with headaches. My feet are always going numb, same with my hands. Sometimes I get so dizzy my vision kind of goes out and I feel like I'm spinning.
