Upper chest pain, left side closer to my armpit. Had it for about 3 years, comes and goes, feels kind of like achy/sharp pain above my heart?

See a doctor. From the type of pain and it's location it does not seem to be anything serious. However it's better not to take any chances so please see a doctor to evaluate and to do atleast an E.K.G. and xrays. He might decide to do more tests if necessary.
Chest pain age ? How old are you 18 or 80? Not enough information. What brings it come or makes it go away? Need to see a Dr would go to walk in clinic.and be checked out.
