7 years out need advice

After not eating for a while,i feel a burn under my breast bone would that be digesting fluids, i don't feel it all the time though. anyone have this problem?

Occasionally my heartburn returns. I isn't just under the breastbone, but more like my entire pouch hurts. I go back on my Prilosec. Unfortunately, every time I go see my surgeon it is OK, and I forget to mention it. I've not matched it to eating any particular food or anything. Sue O.
