Thank you so much for the detailed account. I went to the hospital for what I thought was a cardiac event. It wasn't thank goodness. The only one who thought that going to emerg was dumb was me. Everyone at the hospital assured me that it was, indeed, better to have a false alarm than have a visit from the coroner.
On another note, my 52 year old friend had a heart attack on Christmas last. But because she was having family over for the Christmas feast, she ignored her symptoms. Yup, she was having a heart attack. Had she gone in when she first experienced problems, which was a few days before, they would have found that she needed bypass asap and would never have had the heart attack. Now that she has had a heart attack, she is at greater risk for another.
So, don't ignore strange symptoms as suggested in the inital thread.
