I have intermittent pain (not severe) around my rib cage. It comes and goes. Almost every day, for about a week. Could this be a sign of possible heart problem. Have no health issues, do not take any meds, am healthy, about 145 lbs, female, 78 yrs old. I have 1 drink every day, and rarely have more. Am reasonably active, still have 2 businesses I work with daily.
