I think Joyce has an idea that may be worth pursuing. After all you have been through, it may not hold out any solutions but certainly worth the effort to confirm what you already know or the chance that there may be some other explanation or options.

This is one of those situations where you are learning more than one ever wants to know. I am so sorry you and Killian have to go through this ordeal. He is so lucky to have a Mommie who tries to hard to help him.
