I have also had a rash on my upper chest and at times on my upper back. I asked my GI doc and he said it was probably dry skin (which I know it wasn't). The next time I saw him, I told him that I ahd been on a non-gluten diet and was feeling better. He asked if I still had the rash and I realized that it had gotten better. He said that Celiac disease can cause rashes and sent me for a test. Unfortunatley, Celiac tests require that you are eating gluten since it detects the inflamatory response of hte body to eating gluten. The test came back negative (of cource since I ahd not been eating gluten).
