Update

So Dad got along excellent yesterday. The Dr. couldn't see anything while doing the colonoscopy but he is puzzled as to why his blood work is wacky. He is going to book him to have a scope done down his throat to see his upper chest area??? I think that's right? He does have something called diverticulosis. This could be causing his pain and some other symptoms but it still doesn't explain the abnormal blood tests. So hopefully things will be ok once everything is complete.
