Brief Answer: Pharyngitis Detailed Answer: Hello Thanks for the query I have gone through the excellent history given by you and here are my suggestions 1. Pharyngitis causes cough and it usually takes about 3 to 5 weeks for it to subside completely 2. However in this case the cough has recurred and this seems to be like a recurrence after stopping the antibiotics, I strongly recommend you to get a chest x ray to rule out pneumonia and complete blood count to know if the infection is still persisting. If there is any phlegm at all i recommend you to give it for culture 3. I also recommend you not to use Cheratussin as it contains codeine which is a cough suppressant, in a setting of an infective eitology it might worsen it by inhibiting the cough reflex ( which is protective as it brings the bacteria out), lozenges like strepsils should be used instead 4. Watch out for fever 5. Avoid cold food and beverages, keep the patient warm at all times 6. Avoid milk, milk products and spicy food items I hope I was of help, if you have any further queries please get back to me Regards
