I have heartburn almost every day unless I take my daily Prilosec otc. I haven't seen a doc for it yet. Should I see about an endoscopy?

Consider one. Perhaps, you are eating and drinking something that precipitate your heartburn- caffeinated drinks, alcohol, spicy foods, energy drinks. This could be the reason why you have continuous heartburn despite taking prilosec. Cut down on intake of these. Be tested for h pylori anitbody. In addition to prolosec, you may take ad if your symptoms are getting worse, consider having an endoscopy.
