W: Good morning, Mr. Brown, what’s brought you here today?
M: Well, you see, doctor, (16) I’ve been having these headaches.
W: Aha, and how long have they been bothering you?
M: Er. Well, (17) it must have been about three months now.
W: I see. And which part of your head is affected?
M: Well, (18) it’s right across the front here.
W: Can you describe the pain?
M: (20) It’s sort of a dull, dull and throbbing kind of pain.
W: I see, and does it come on at any particular time?
M: They’ re usually worse in the morning. I notice them when I wake up.
W: Mm. (19) And is there anything that makes them a bit better?
M: (19) Well, if lie down for a while, they go away.
W: Yes, and has there been anything else apart from these headaches?
M: Well, my wife says that I seem to be getting a bit deaf.
W: Oh? Well, Mr. Brown, I think at this stage I’ll start by checking your ears.
