Hello Dr. Grief, I have a history of eczema since childhood, but as an adult only have itching below skin surface water blisters on fingers at different times. For the past 5 or 6 months, however, the first two knuckles on both of my hands have become very itchy, somewhat swollen, and so dry that they split, crack and almost bleed. None of my eczema medications have any effect. My cousins have celiac disease and gluten intolerance and today mentioned that I could be showing symptoms of that. What do you think?
