Well, my tests turned out OK--I think. The echocardiogram didn't seem to find anything wrong with my heart, which is great. The carotid ultrasound went well, although the specialist didn't want to talk about it--she said that my doctor would get the results in a week. She spent a lot of time sounding out the area just under my left ear--I wonder what that meant? Oh, well. Bloodwork is the next step, I guess. I'm coming more and more to the conclusion that it was my high triclycerides and caffeine levels.
