I am having chest pain/pressure on the left side, right side headachein back head,acid reflx,& nervousness.I also feel very fatigued,lightheaded, nd the pain goes from the upper left side of my left breast to the right side of that left breast.I am really scared.I did end up in ER a couple of weeks ago, they ran labs,did an ECG and said that it wasn t my heart.I sometimes think, even though they told me it wasn t a heart attack,I still think it can be heart related. I am a single mom w/2 kids and unemployed. Can you help me?
