So it goes like this:

Since January, I've been having Celiac symptoms, as I see it.  Fatigue, bloating/awfulsmellingflatulence when I eat certain foods (not quite sure what, I think gluten), irritability, sleeplessness, depression, mysterious sinus headaches, and general dizziness.  I've gotten tested this summer for sprue a couple times, and both have come out negative.  I told my doctor, who is very experienced, that I didn't think the blood tests were very accurate based on what I've read, and he said that they are 99.9% effective, the ones that he'd seen done.  Anyways, today I tested negatively for lactose intolerance as well, and I'd had a biopsy done earlier, which was part of a colonoscopy.  They saw some enflamed tissue and I was (mis)diagnosed with Crohn's, but I really don't have a lot of Crohn's symptoms, I don't think.  The biopsy was negative for sprue though too, I guess.  Anyways, I'm not sure what to do at this point.  I've cut gluten out of my diet, and it seems to be better, but then again, I've cut a lot of things out at this point (everything but meat, fruit, and veggies).  I...don't know what to do at this point.  Any ideas?
