<<Disclaimer: Verify this information before applying it to your situation.>> Linda, Have you ever had the small biopsy done to confirm one way or another whether you have the disease or not? Perhaps you have had it all along and your son received it from you. Just a thought. If you have responded well to the diet my suspicioun is you may have the disease. Anyone else care to comment.
