W: Hello, I’m Jenny Johnson. How are you this morning?
M: Hello! Doctor Johnson, I can’t say I’m feeling well. (1)I have a pain and swelling in my knees.
W: What kind of pain is it?
M: It is a dull ache. But sometimes the pain is constant, and disturbs my sleep.
W: How long have you been feeling pain in your knees?
M: For about two years. But recently, (1)I feel pain in my fingers.
W: Have you had any swelling in your fingers?
M: Yes, a little.
W: How about your wrists or toes?
M: No, only my knees and fingers. The pain becomes worse when the weather changes, like in cloudy or wet weather.
W: OK. Let me see your blood test report first.
M: How is it?
W: Not very bad.
M: Do I have to have an operation?
W: No, I don’t think so. (2)I’ll prescribe some traditional Chinese medicine. Also you need a treatment with rays below the red in the spectrum.
M: Do I have to come here every day for the treatment?
W: (3)Not every day. Can you come three times a week? A course of treatment includes 20 times, so you have to come for the treatment three times a week for seven weeks.
M: How long does each treatment take?
W: 30 minutes.
M: OK. I’ll do that.
W: (4)When you are at home, use these hot water pads as often as possible. Put one over your knees. Try to avoid using cold water.
