Dry cough

John came home on Saturday from his surgery/hospital stay. He did amazingly well in the hospital. He is on a feeding tube 16 hours a day. We start it when he goes to bed and he is done around noon. This way he has the afternoon and evening 'free'. He is eating small meals and tolerating them well. But the past 2 days he has developed a dry cough. I thought I would ask if anyone else had this. His lungs are fine. I thought it might be our heat. We have radiator heat and it can be dry.
