DS has had a cold for a couple of weeks. His cough seems to be getting worse (he does have asthma triggered by colds). Today out of the blue he just started crying and said his ear hurt. About 20 minutes later he was crying again because he couldn't chew his goldfish on that side because his tooth hurt. At that time I saw yellow gunk coming out of his opposite eye but didn't think much of it because he had been crying. He had no fever but I did give him Advil. He laid on the couch the rest of the night which is not him at all. I just put him to bed and the yellow gunk is just coming. He wipes it away and more comes. Now that eye is bright red. I'm sure it's pink eye of some sort. I also think maybe he has an ear infection. Can they both just come on that quick? Mom stopped by this morning and said he looked pale, but he always looks pale so I didn't notice it. Maybe she was on to something. I called and left a message with the pediatricians office, as they have Sunday morning hours for sick kids. I normally wouldn't go in so soon but he's had a could for almost two weeks and I think this may be a secondary infection of some sort.How do they tell if pink eye is bacterial or viral?
