I have been experiencing these symptoms for a week, it's worse when I drive, I've even felt panicked about it. So of course I googled to see a bunch of crazy things pop up. Now I'm scared. Went to 3 different docs (general, pulminologist, cardiologist) everything checked out but they gave me Nexium and Zantac 150... And xanax for if I feel panicked. I'm at a loss. Will this eventually go away? Please help!
