Dan,
Our prayers go out to you and your family for your sons health. As stated earlier modern medicine has come a long way. As a parent I know at times you'll feel like there's nothing you can do, but God will be with you always. Last week I felt that, as my daughter went to the emergency room for cramps and 8 hours later into surgery for appendicitis. She's recovering just fine. If you have medical questions that haven't been answered or don't understand my father-in-law is a doctor and I can ask. Shon
