I have had anxiety on and off for the last two years and have had chest pains and headaches. i have had like 4 brain ct scans in the last year all normal. i saw a cardiologist who did a stress echo test one year ago and the repeated it 6 months ago all was normal. i did a endoscopy which showed hiatal hernia and acid reflux. I visited the ER maybe 25 times in the last year.I have this chest pain again and feel like when i breathe i get a sharp shooting pain in my chest and feel like i will faint and pass out. could this all be anxiety i am worried something serious is wrong
