So I went to my doctor today.
I thought he was going to tell that its nothing to worry about - and he (eventually) did. But I was a little taken aback by his concern that I wasn't taking it more serious.
I explained the type of pain and where it hurt and asked, "I know its not a heart attack so what else could cause that pain?"
His immediate response was, "why wouldn't you assume upper-left-side chest pain is a heart attack?!"
We talked about it a bit more and he's pretty sure this time it was gastronomically related, but told me to not be so casual about it next time and to let him know instead of waiting two weeks to bring it up.
