Stomach pain for 15 days especially two hours after eating.? Saw doctor and had blood tested and found nothing wrong with liver or gallbladder. No gal stone or stomach after finding from ultra-sound. Took antibiotic Erythromycin 250 mg two per day for 13 days and then stopped. No pain after taking medicine but stopped recently and after 4 days without medicine the pain come back today. What you think is wrong with me? I also had a colon checked on May 2005 last year and found four polys and cut them out but was not cancerous. Thanks for any idea. Doctor has told me I might have IBS. I do have a bridge on my front teeth and casuing foul bad smell. Is this causing my problem? Maybe the bridge on teeth have bacteria that come down to the stomach and become bugs and growing inside. Any idea? I was thinking of taking my bridge out and use a denture instead.
