Update...Good News Sort Of

We finally went in to see the doctor yesterday and got some good news. First of all TM's heart is perfectly normal, if not above average. They ruled out a heart attack. Pheww!
The sort of part is that they still don't know exactly what happened. What they are thinking now is that it is one of two things. One is that his glucose levels were high when they tested him in the hospital, so they think that he might have diabetes. He has several other symptoms, including the fact that his dad is insulin dependant. We did some testing and are still waiting to find out the results.
The other thing that they think could have caused the symptoms is that his potassium levels were really low. As the doctor said that is "weird". If that is it, then all he needs to do is eat a banana a day. How great would that be if that was it!
Either way, he is doing a lot better, and we are feeling like we can see the light again. Thanks to everyone for all of the support and prayers on his behalf.
