Cant breath sitting standing walking a few feet. chest is real tight. im shaking all over cant eat. when i lay down it completely goes away.oh and my?

Sounds like ER time: New chest tightness and difficulty breathing are signs that that a woman in her 60's could be having a heart attack and needs the ER. Usually, the paramedics can help quickly. A patient can call 911 or the local emergency number. If it turns out not to be an abnormal rhythm, heart attack, anxiety attack symptoms, a collapsed lung, or pneumonia, the ER will still have been the right place to go.
