Hi I have been experiencing dizziness, nausciousness, weakness, pain in my upper back and pressure in the middle of my chest - but the chest discomfort is not pain but a presssure and it s not all the time but enought to have me concerned. - all of which comes and goes but is happening daily now. Its was every so many days at first but for the last week its been daily and the dizziness is worstening. I have high cholestoral and my last check my ac-1 level was 6.4 but may be elevated. I do not take any medicine. Not sure whats going on but something is wrong. Not sure what kind of doctor to see or should I go through the emergency room. What do you think?
