I'm sorry you're having a rough time, Aloysius. Hang in there and Anthony will answer your post. I really dont' know what to say. I'm having trouble following you and I think it's because I have no idea what some of the military stuff means. I understand that A.O. is agent orange and that you are trying to see if there are connections between A.O., PTSD, and Emphysema. I have no advice, but just words to encourage you. You keep going until you find the answers you need. I hope you find them.
