Im 18. Male. Been dizzy for over a year on and off then about 6 months ago I had a feeling like a heart or panic attack and have been dizzy alot since with sometimes rapid and pounding heart rate. I had ekg, holter monitor, blood test, many tests done... All seemed fine. I was put on anxiety medicine a few weeks ago and it may have done a little but im still dizzy and still having rapid pounding heart beats. What is it? Help?

Do you drink plenty of water? Do you drink caffeine?

If you've had tons of tests and the doctors say you're fine, then you're probably fine and it's probably anxiety.
