I'm really scared right now I'm 31 yes old and being suffering from heart palpitation since I was 26yrs old. I was in a stressful relationship on and off for 10 yes that's over. I started a job 6yrs back as a nurse assistant that's when I had my first panic attack man it was bad. After that I worked about 6 yrs in a stressfull enviroment I quit that job. Long story short I also suffer from anxiety too. I recently went to the ER for a panic attack I felt like I was going to pass out couldn't breathe the doc ran a blood test,EKG checked my o2 everything my liver etc... Test comes back normal. Why does it feel like my heart is going to stop. I tried to work out to help with the palpitation but it made it extreamly worst I felt light headed and my legs and hands were tingling and it sounded like water was running in my ear I was so scared I didn't get off the couch for 5 hrs. I get scared when the palpitation happen and more come. It seem like the palpitation started when I worked out not after the panic attack. And the work out was tough now its been over a week since I stopped working out and the palpitations are still there . I so sacred right now i all I want is someone to help me. Sine my heart palpitations began when I was 26 it seems like everything stresses me out including working out and before I was able to work out with out the palpitations.
