W: Hi, Martin! So what’s your problem?
M: Well, recently I’ve been getting this pain here, just behind my eyes and in my forehead.
W: I see. Have you felt sick or dizzy at all, or vomited?
M: No, not at all, though the pain is pretty intense sometimes.
W: And how’s your health generally? Have you had any colds or flu recently?
M: I had a cold a couple of weeks ago, but that’s gone. It was only a sniffle really.
W: Good. Are you studying a lot? Are you getting enough sleep?
M: Yes, I’m studying quite a lot—I’ve got some exams coming up in December, but I’m making sure to sleep plenty.
W: What time do you go to bed?
M: Usually around 11. I’m up about 7.30 so I have time to go jogging for half an hour before going in to the university at 9.
W: Very healthy. And has this pain kept you awake or stopped you jogging?
M: Yes, it makes getting to sleep harder. It’s much worse at the end of the day. I hardly notice it in the morning.
