It is impossible to remember it all. Initially, I limited myself to 5 questions. But, I also always let the doctors speak first. I found that the doctors frequently answered my questions before I asked them. I also didn't want to disrupt the doctor while presenting what he/she felt was important. Ever sit in a class where a fellow student never let the teacher finish a statement? I personally don't learn like that. Ever try to teach a class with students like that? It is quite difficult to teach the subject matter. Now we all learn differently. Do what works for you. But if I listened to a recording of a doctor's visit, my head might explode. It already comes close just reading the doctor's post visit notes.
