About a year ago I was diagnosed with cealiac disease. I had a colgnoscopy done and had polyps removed. Was going a lot better but now a year later I'm tired , my hands sometimes shake very slightly but I notice, I have very bad pain in back area . Seem to develop an allergy when I eat egg. Never had allergies. And in my left armpit and occasionly right seem to hurt I've heard there`s lymph nodes there.. I tell my doctor he doesn't seem to look into it, does a blood sugar test. I basically had to diagnose myself with the cealiac he just confirmed it with the colnoscopy. I'm changing doctors but does anyone know what the problem could be. I'm worried about under the arms.

Here is a really good site on cealiac disease. Celiac Disease (http://digestive.niddk.nih.gov/ddiseases/pubs/celiac/)

It is possible you could have other food allergies as well
Try eliminating other things from your diet like the eggs, sugar and processed foods with preservatives and see if that helps any.
