Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that your son is suffering from viral infection leading to stuffy nose,
fever,
bad breath and pulling at ears can be due to
ear infection causing earache..
I would suggest you to consult a Paediatrician and get him evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis and treatment can be done accordingly..
As of now you can give him
Acetaminophen to reduce fever and will also reduce pains..
Put saline nasal drops to loosen mucous and drain it off and relieve congestion..
You can give him steam inhalation and use a humidifier in his room..
Give him plenty of warm fluids and sufficient mother's milk..
Give him appropriate rest..
Hope this information helps..
Thanks and regards.
