My 6 y/o son woke up this morning, his ear was bright red and a little swollen, and he said that it hurt. He still went to school, but when we picked him up, his ear had swollen to twice the size. We thought it might had been a bug bite or something, so we gave him some antihistamine and cordisone, but it doesn t seem to be working, and now he s complaining more about the pain. Any suggestions?
