Eye Burning Related to Food Sensitivities

I have collagenous colits and a list of other problems that my GI doctor seems reluctant to address. I have horrible burning in my eyes with a puffy feeling around my eye area (no actual inflamation) and stomach aches/pains, fatigue, headache, and facial flushing/redness to name a few. He told me to see an eye doctor and referred me to a rheumatologist. My eyes are good and was told I have dry eye and to use drops. I got literature on fibermyalgia but I''m not interested in more drugs. The rheumatologist also told me to take sleeping pills, exercise, and use eye drops and that I shoudl see a GI doc for the stomach problems. I am incredibily frustrated because I feel sick every time I eat and the eye pain/burning never goes away. I've been tested for celiac disease several times and it always comes back negative. I am not lactose intolerant. I tried an elimination diet religiously for 4 months and removed all processed foods, wheat, dairy, and yeast. I didn't notice a signficant change in how I felt. At that time, I didn't have the eye issues. I've read that the eye problems can be related to food or could also related to liver problems. My blood test show my liver is good. Any ideas would be appreciated because I seem to be on my own. I keep complaining of ill health but all my tests keep coming back good. I am afraid to eat and I want my life back.
