Hey Echos. My husband has that same pain. Goes from his ribs down to his groin area. And he gets bloated. He has Crohn's. Sometimes his back and stomach hurt so much, he gets sick to his stomach from the pain. I don't know if this is why your having this pain, but it's somthing to check into. Also his pain will last anywhere between 3 days to 3 weeks (it's called a flare up). I hope you can find a doc soon to get some relief
And PS: If you can't get any pain meds for it, try warm compress and steer clear from dairy or wheat foods. Those will make the bloating worse. Hope this helps
