I have been experiencing intense bouts of nervousness, dry flushing and nausea for months. These “spells” come on quickly and pass quickly. They happen a few times a week, which doesn’t sound like a big deal. But this feeling is so frightening! I’ve had heart, blood and urine testing. Everything comes back “normal”. I am a fit 70-year-old woman, so I can’t blame this on hormones! I’ll be at Mayo for my annual physical next month thank goodness. If my symptoms have a name, they’ll know it!! In the meantime, I’d appreciate hearing from anyone who has similar issues!
