<s>[INST] my 34 months old son is having a stuffy nose for a couple days now. Hes got no other symptoms aside from the stuffy nose and every time he blows, the mucus is greenish in color. He had an ear infection recently. I was wondering if I could give him fenistil to help clear it. [/INST] Thanks for posting your query on Chat Doctor! I appreciate your concern for your son. Apparently he is suffering from upper respiratory tract infection. Since the color of the mucus blown is greenish, so I am of the opinion that he is having bacterial infection and that too Pseudocodes has to be ruled out. Take an opinion of child specialist since recently he had ear infection. The doc might prescribe definite for your children illness. Best regards/1 </s>
