The large bowel enema will only look at your large bowel not your small bowel, to get this checked you need specifically the small bowel enema. I had the large bowel enema done and isnt too bad, bit uncomfortable but manageable.
The small bowel barium is when you have to drink the liquid and they take several x rays over a period of a few hours.
I had pain under my ribs on the right side going all the way down to where my appendix were, also i had pain around my naval. My gastro doc told me that crohns often gets mistaken for appendicitis because of the location of the pain.
To test for crohn's in your case i would recommend the ESR blood test, small bowel barium enema and the gastrograph follow through. But this is just my opinion remember.
Before i was diagnosed with crohns i put myself on a low residue diet (which is recommended when crohns is flaring up) and i actually got some relief from the pain and other symptoms. Try a low residue diet and see how you get on with that.
It's up to you if you tick the box in the same colour pen!!!
who knows the doctor may have forgot that he ticked the ESR box!
You really need to get your doc to refer you to a gastro if he hasnt already done it. If he has change your gastro doc. What area in the uk are you?
by the way dont be surprised if your liver enzymes comes back raised, mine did every time i had my bloods taken, the reason behind this was because my crohns was left untreated so it caused inflammation of alot of my other organs.
