So my breathing has been somewhat stressed lasely. Doctor says it's from my anxiety. Gave me Albuterol inhaler and I'm taking lorazepam. Seemed to be getting worse over the last couple of days, but this morning breathing was fine, but I had jaw neck and back pain. Anxiety kicked in since these symptoms apply to women having heart attacks. No chest pain or difficulty breathing. No nausea or sweating. Just this alignment of discomfort. My pulse rate was between 60 and 66 the times I took it. I'm worried because I've gone to the ER with these a rapid heart beat AND these symptoms, and I've been told that nothing is going on, it's the anxiety, but any site I go to listing symptoms of panic attacks says to go to the hospital if jaw, neck, or back pain manifest. I guess I want to know if anyone's experienced this and if it's possible to have a heart attack without having a rapid heart beat.
