Hello dear, I understand your concern. In my opinion the presence of ear clogging,laryngitis,cough after the flu is seen commonly. It needs symptomatic treatment like decongestants,any cough syrups etc. Take lukewarm water for drinking. Flu is caused by a wide range of viruses. Flu sometimes might cause secondary bacterial infection where in you might need a course antibiotics. So I suggest you to consult doctor for physical examination to rule out any bacterial infection. Nothing to worry. It will subside mostly with symptomatic and supportive treatment. Hope this helps. Best regards...Dr...Srilatha
