I don't know if what's been happening lately is a new symptom or something else entirely. I'll be standing , doing nothing in particular, when I'm suddenly overcome with dizziness so severe that if I don't hold onto something I'm headed for the floor. It doesn't last long, but it's enough to scare the heck out of me. Afterward I feel just fine. Went to the cardiologist not too long ago and he said the tests were all great and my heart is fine. My blood pressure is good, and my tests in general are pretty much normal.
Not sure where to go with this. Any ideas, similar symptoms or suggestions? I'm really nervous about this one.
