Any advice on how to make a swine flu cough less painful?

He needs to be taking some tylenol or motrin regularly - motrin works best for this. Adult dosage is 600 mg to 800 mg every 6-8 hours. Continue with the cough medication regularly, increase his daily water intake which thins the secretions and decreases the amount of coughing he does, no smoking and running a humidifier in the bedroom where he sleeps - all will help him get well. He may be left with a residual cough even after he is well - this is common.
