as is said in the business "time is muscle' , meaning that the more time you sit on chest pain the more heart muscle function you may be permanently losing - which means a lifetime of heart failure (or worse).
As others have said - it may be something unrelated to the heart, but best not to take that chance.
get it checked out pronto !
Sometimes there are 'warning episodes' before a major heart attack. please don't ignore!
