my granddaughter has had severe stomach problems since January. Has had H pylorai, gall baldder removed and now 3 weeks later STILL has severe mid section stomach pain and around in her lower back. HAd all kinds of scans, tests, xrays, mri , etc. NOTHING WORKS! taking bentyl , hysmanex, dexilant, . I finally put her on pepto bismo tabs and they seem to help stomach, not back
