My son has/had an ear infection. About two weeks ago we took him to the ER because he had mucus coming from his ear. They put him on antibiotics. He was on meds for ten days he's finished his meds but his but his ear is still draining mucus. He has an appointment on the 11th but I really don't wanna wait that long. He isn't bothered or running s fever but I still wanna take him in tomorrow. Ugh
