DS was up alot of last night screaming (according to DH, I was fast asleep) DH thought it was his ear but this morning he says his eye hurts and it's quite red. I noticed it red rimmed last night but he was tired so I thought it was that. He keeps blinking and almost trying to focus on things. He was bandly knocked on the head on the same side at preschool - could it be related? Shall I take him to out of hours doctor or is it OK until morning? It looks only kinda half open...
