Hi, energizer! I *have* experienced that, occasionally, not as chronically as it seems you are, but it was one of the many recurring symptoms I experienced this spring. I've had some of the basic heart tests, and a whole schwack of other tests, which found nothing unusual. At some point this spring, I determined I was allergic to ginger and I believe I was developing a stomach ulcer because of ingesting an allergy. Since then, the most common pain I experience seems to be coming from my stomach (which seems to be a lot higher than I would have thought!)... just another avenue for you to investigate... oh, and I found that DGL (a chewable licorice root tablet) is extremely helpful with this kind of stomach ailment.

Good luck with your search, but by all means, don't stop looking until you figure something out!! Let us know what you find out, too. (the info on costochondritis is pretty compelling too, if/when the pain occurs again I'll check it out myself)

It's unfortunate, but we have to be our own advocates for a thorough diagnosis. I guess it's not that bad, after all, we are our own warranty on these bodies, so we might as well do the best job!

Namaste,
