[|Human|] hi my son who is 6 always seems to get a dry cough every few weeks or months sometimes with  a runny nose sometimes without. He had pnemonia at 17 months however the doctor said his lungs were not scarred. Is it just a viral infection or could there be more to it?
[|AI|]  HI, Welcome to Chat Doctor! I am sorry learn about your sons condition. Yes, Chat Doctor.  He might be suffering from headaches and body aches, which as also common symptoms of Viral infection. If he develops sputum in his cough (yellowish), it may indicate bacterial infection. As you must be aware, viral infections have no treatment and are self limiting. They take 8-10 days to cure. Till then, only symptomatic treatment may be offered for cough and runny nose. Hope this information helps. Feel free to ask if you have any doubt. Wishing your son a speedy recovery. With warm regards,
