My ds6 has a gunky ear, he woke up during the night last Monday crying and saying his sister had put water in his ear, was awake for a couple of hours but fine the next day. The next morning when he woke up I noticed a discharge on his pillow and in his ear but he hasnt complained of any pain, its been like it every day and still is. He only says it hurts when I wipe away the discharge with cotton wool, Im not doing anything inside the ear though. He had grommets when he was 3 yrs old and again at 5 years old but we have never had discharge like this before. Im assuming he has an ear infection, no temperature though. Will this clear up by itself or does it require antibiotics?
