I just got off the phone with our doctor and she said all tests came back negative for Dallas. This is great news. Hopefully, it was just a terrible virus. We are going to keep him on his meds for another week, and then gradually throughout the next month, we will introduce him to milk products and then eventually gluten. If at anytime symptoms reoccur we will reevaluate and see if gluten or milk products are the problem. So, strict diet for awhile, but probably not indefinately. As you can see, he has lost some weight, however his appetite now seems to be back.
