Karen, I know that pain only to well, first Heart attack I had a clean EKG was sent home, I was having a heart attack for 3 days before I was finally diagnosed. I had another attack 2 yrs. Later, now I have two stents with left sided heart damage. My pain was in the chest ,jaw,left arm. If you start feeling that pain again keep going to the ER till you are taken seriously, never feel like an idiot.
