<s>[INST] My 8 year old son has had a wet cough for a month now. He is now complaining of a headache, stomach ache, sore throat, all over general body pains and is having difficulty sleeping because he continues to cough, waking himself up and has a sore throat to go with it. I took him to the ER where they decided it was a sinus infection and gave him anitbotics which he has just started today, however I am concerned there may be something that is being over looked since they did nothing but listen to his chest and take his temperature, which was slightly above normal. Not sure if I should let it go and cross my fingers, or take him back to the ER. [/INST] HiT hank you for asking ChatDoctorI have gone through your query. Usually with sinus infections patients get feeling of heaviness of head, nasal block or stuffiness, but cough also can be present due to secretions from posterior nasal area or irritation. In such case an examination with otorhinolaryngologist will be well appreciated. If his lungs are clear we can rule out a lower respiratory infection also. For sinus infection I treat my patients with antibiotics like Co-amoxiclav nasal decongestants and vitamin C. Those who are not getting relief after this I advise paranasal sinus X-ray and puncture of sinus if needed. Hope this may help you. Let me know if you have any further query. </s>
