Re: pain under rib cage right side and into the back
Definitely anything is possible. I would suggest you push for an abdominal MRI (called an MRCP).
Is it possible you have adhesions from your surgery? I don't know what would show that you have them.
Have you had a colonoscopy? If he's thinking ulcer, then you need to have a test for h.pylori and an upper scope.
You definitely need to go for the follow-up and get the results (and copies) of your bloods,
How are you eating? what does a day in your life diet look like?
What meds has your doc given you...have antispasmodics helped to ease some of the discomfort?
Ihope you find the answer...it's difficult to hear, because I can relate to discomfort in the abdominal area. I do have ulcerative colitis, had a hysterectomy (which helped with much of the discomfort), but flaring, food choices, etc can definitely exacerbate some symptoms. Gas can bring me to my knees sometimes, and some food changes can help.
The transverse colon and the bends in the colon from the right side and left side can cause confusing symnptoms.
Oh, have you had stool sampling done as well?
It's all a matter of perspective!
