Is It Celiac? in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted June 4, 2010 · Report to Admin It really does sound like an ulcer to me, too, and with those symptoms you should probably see a doctor as soon as you can, because ulcers can get worse if they aren't treated. It could also be something like a hernia or some kind of blockage, and for those things you should also see your doctor. But my dad gets ulcers (and he has celiac as well) and what you describe sounds like the symptoms he has when he has an ulcer. Ulcers can be caused by a number of different things, including bacteria, so it's possible to have one even if you're not stressed out. I hope for your sake that it's not celiac and that whatever it is you can get it sorted out quickly! But basically with any kind of pain that is sharp and comes on suddenly like that, it's good to see your doctor as soon as possible.
