My son underwent coblation adenoidectomy on dec 5th for having grade 4 adenoids. Post that he is having glue in left ear which turned into puss later and got cured by antibiotics however he still have glue. Today after 25 days of surgery he caught cold again probably on use of chalk piece at home. Yellow mucus day 1 and day2. Cough n vomit in afternoon sleep. Mouth breathing since 2 days. We are continously giving medicine either for ear infection or cold even after surgery. Medicine  given zyr cold pulmoclear refzil o 125mg syrup morning and night. My worry is why is my son recovering yet. He is 2.5 year old We do not know if the cold is now triggering again due to allergy or viral cold. And how long does it take to cure ear fluid. Please suggest and guide us if we are going in right direction
