question: My 12 year old has been sick for 2 weeks. started with congestion and typical allergy symptoms then he started running a fever. tookto Dr found 2 severe middle ear infections started amoxicillin 7 days later his fever is higher and has a persistent cough. He has now been on z pac for 3 days still has a low grade fever cough and head aches I am considering taking him to the ER as I think there is more happening here. We did blood work to rule out pneumonia, mono, kidney failure and leukemia
