I am glad that the pain went away sooner rather than later...I think if I were you, however, I would call the doc and make him aware of this then see if he wants you to come in...It might be some comfort to have a repeat ecg and echo.
The good news is that you are not still hurting. I have pains in my chest like that. It unnerves me when it happens...perhaps it is chostrondritis. or do you have any problems with GERD? sometimes I think that the severe pain is coming from the esophagus.
I am glad to hear from you,
I hope that you feel better soon,
I have promises to keep and miles to go before I sleep, and miles to go before I sleep.......Robert Frost
