M: Good morning, Doctor.
W: It’s Mr. Commen, isn’t it?
M: Right. I saw you about six months ago with the broken finger.
W: Yes, of course. Is it all healed now?
M: It’s fine. No problems.
W: What can I do for you today?
M: Well, I’ve been having these headaches. They started two months ago. They seem to come on quite suddenly and I get dizzy spells as well.
W: Right, let’s start with the headaches. Where is the pain exactly? Can you show me?
M: In the front. I thought it might be my eyes.
W: Did your headaches come on at any particular time?
M: Yes, when I go to work in the morning, when I step outside my shop, I run a boutique. My shop is just nearby. So when I walk out, the headache comes on.
W: Do you ever have these headaches at night?
M: No, I’m not sleepy at night. I wake up two or three times every night.
W: Why is that?
M: Well, I think I’m a bit of worrier. We had staff problems at work and the financial situation is peculiar at the moment.
W: I’m sorry to hear about that. Can I just come back for a moment to these dizzy spells? Can you describe them?
M: Well, they last a few seconds, I suddenly feel very dizzy.
W: This dizziness, for some people, it’s a sensation of falling; to other people, it’s a sensation of fading. How would you describe your dizziness?
M: I feel that I am going to fall down.
W: About your health in general? How do you feel in general?
M: No problems beyond a cold, but that’s about it.
W: Ok, let me give you a check-over.
