I have episodes of burning in my left chest area about 1-2 hours after eating. This seems to come and go usually lasting about a week or so. I have had a scope inserted down my throat to look for stomach problems-nothing found. I am taking Prilosec every day which did seem to help at first, but now the pain is back. It seems to get better if I get up and walk around or work out. It is much worse if I am sitting after I eat. Any advice on what is going on? I am eating a very bland diet now and trying to stay away from any spicy, fatty foods.
