I listened to you on WCCO radio this afternoon. I was interested in what you had to say and your book. My brother in law was a medic in Vietnam. He was in Pleiku, An Khe, QuiNhon, Saigon and Cam Rhan Bay from 3/70-2/71. He is very ill with an undetectable illness (cancer) Do you know of any resource for finding vvets who have symptoms of AO that he could compare his symptoms and what their diagnosis was? Desperate!
