dande5,Wow! I have about the exact same symptoms as you, and we are close to the same age (I'm 28), too! I have sharp, stabbing pains behind my belly button. I also have pain in my back, between my shoulder blades, I belch a lot, and I have gas pain with constant bloating. I mainly have D, but alternate to C a few times a week. I also reflux stomach contents up my throat occassionally.I have been told I have GERD (in addition to IBS), and I take 40mg of Prilosec a day. You really should be tested for GERD, and H. Pylori. I was diagnosed with the H. Pylori bacteria when my symptoms were at their worst. It can make you feel really bad!Ain't it fun being us?!
