I haven't seen a doctor, but I'm pretty sure I have it. I'll sometimes have a racing heartbeat, accompanied by lightheadedness and a tightness in my chest. I've read that this can be your heart trying to produce more blood, which makes sense in my case, because I have low blood pressure, due to blood loss from diverticular bleeding..
Sometimes I get very dizzy and lightheaded when standing up, walking, or going up the stairs. The other night I couldn't even walk across the room without almost passing out, and I had to lay down as soon as I went upstairs.
I had the flu a few months ago, and the dizzy spells/weak feelings got a lot worse then and stuck around for a long time afterward. I'd feel fine as long as I was sitting down, but once I was on my feet, forget it, 'game over'.
I'd also be interested in anyone's advice on how to deal with POTS.
