Can you spell the name of your disease? Do you know the name of your diagnosis, and the specific variation, if it is one with many variations?
When many people go to the doctor, they get a verbal diagnosis "it seems you've got mumble mumble", and a verbal treatment recommendation "I'm going to put you on mumble mumble, take n pills a day until it runs out and we'll see what happens." You get a written prescription, which you may, or may not be able to read.
