I've never had problems with fainting. I completely blacked out for a minute. I went to the ER, and they did a basic work up, ekg, some blood and urine tests, Ct scan,Cutarad Duplex ultrasound and chest xray Everything looked normal.
One week later, it suddenly hit me again. This time my eating and drinking were normal. I was standing on a deck and it started spinning. For several days after that, I would have close calls.
Went back to work, and thought it was all better.
