lxg17..I'm 44 - my pain is a "pulling" pain (like a muscle strain)just to the right of my belly button, sometimes extending outward to the right. I've had it for about three months, no major bowel changes or other symptoms, bloodwork fine. Nothing specific triggers it, but it worsens with activity (yardwork, especially when bending down,etc)and/or stress. Doctor doesn't think it's a hernia, cancer, ulcer, muscle pull, bowel obstruction (had a colonoscopy a few years back) but wants to do a scan anyway thinking it might be some sort of rare organ malfunction or inflammation. Any of this sound similar to what you're experiencing?
