I'm lightheaded and dizzy and my heart is racing. I just checked my blood pressure and its 128 over 75 (which is pretty good) but my pulse is 94. What in the world? o_o Maybe i need a nap. I'm not on any medications either and I did eat a couple of $1 sandwiches from mcdonalds about an hour ago and I am well hydrated. Is there a doctor in the house?
