Since June 24th, I've been to the ER twice with a 2-3-day stay. I'm experiencing Presure in my chest, around my heart, and my left arm. Sometimes I feel like I'm gonna just fall out, as if someone is draining all the energy out of me from my head to my feet. While in the hospital, all heart related tests were done and came back neg. However, I'm still having the problem. My pulmonary doctor suggested to have my primary check for acid refluc. Sometimes I get dizzie, and a feeling that my windpipe is being squeezed. What are your thoughts?
