D: What's wrong with you? 
P: My head hurts badly. 
D: How long has it been like this? 
P: Since last night. 
D: Do you have a sleeping problem? 
P: Yes, I even can't fall asleep these days .
D: I think you'd better have a further examine, and before the result comes out, try to relax yourself and take the medicine before you sleep. It will help you to kill the pain and make you sleep well. 
P: Is it serious, Doctor? 
D: When the result comes out, I will tell you about it. Remember, never be afraid or be too tired. 
P: Ok, thank you, Doctor.
