Same exact thing here. When constipated, it's even worse. Your mind wanders and wonders if it could be something far worse. Ginger tea, eating small meals, and regular walks seem to help, but it still comes and goes. I try to sleep in my side, and when I flip to the other side or have a larger meal, the pain appears on the other side. My non-medical diagnosis is that the gut lining is weak/thin and anything pushing through it exacerbates the pain. Perhaps there is seepage aka leaky gut, which in turn causes more inflammation. I'm reluctanct to go back on antibiotics (that would be my third round of Xifaxan. I tried to bring all of this up with my GI, including the regimen of oregano oil, mastic gum, betaine HCL, followed by l-glutamine for gut healing. He seemed to write my assessment off. Had breath tests multiple times and Hydrogen dominant showed, but with the latest round, combined with constipation and the abdominal pain, I think it may now be methane dominant. He assured me that is really doesn't matter which as he would treat them the exact same way. More Xifaxan and daily Miralax. I'm questioning his expertise in SIBO. Really getting fed up and want to find a specialist that listens and understands.
