Hi, I have posted once before regarding atrial fibrillation and severe anxiety. Anyway, I had a carotid IMT ultrasound and the results came back average. Doc said it was a little above average but not enough to be called moderate so he called it average. Not to worry, great news. Well, guess what, I'm worried. I'm also worried because I get this "weak" type feeling throughout my body, I feel lightheaded, kind of faint. From what I've read here, everyone says it sounds like anxiety. I have no underlying heart disease (they haven't found any yet anyway!). Can these feelings really be anxiety? Thanks for your time.
