in the back and front like you describe (I have a congenital defect-- so it is with me for life).

But when it is GI there will eventually be gas, frequency, diarrhea. It might be a couple of hours later, but it will become that.

With no change in bowel function, I would suspect the back.

But I will also throw out there the ovary... so you might want a gyne exam.

Yesterday I went to the doctor for more tests.
I had x-rays for my neck/collarbone, and other things.
She found silent urinary tract infection --I have no symptoms. So I am waiting for a culture now.

But while pressing on my abdomen, she found a hard lump about the size of quarter. I couldn't feel it really, but she was all into it. It is on the side where
my redundant colon is looped, and near my C-section scar. Just another thingy to worry about! I think it is an adhesion in the fascia. She is going to keep an eye on it...and heavens--I hate to think what will happen if it changes! She agreed with me it didn't feel deep, more like in the muscle or tendons. Of course, I didn't know it was there...who goes around pushing on their stomach? esp mine with its weird things beneath? LOL
