How could I forget? What was your "normal" B12 level? Also check The Gluten File, way bottom down on right bar, for a page on B12 deficiency and symptoms. A "normal" level shouldn't always pass.

B12 deficiency can cause some of the symptoms you describe... including bowel urgency, being off balance, foot pain, etc.

Hard to say if you are experiencing peripheral neuropathy or ataxia (possibly with foot pain, off balance)... but gluten sensitivity can also cause those things.

Also forgot to mention... mucous in the stool is a common finding in gluten sensitivity/celiac disease. Also is h. pylori.... there is a page on that in The Gluten File, too.

I'd call that GI doctor by telephone, and tell him your blood test results, and ask if he'd recommend a biopsy. If not... I'd probably look for a different doctor!
