My 11 week old keeps putting his hand up by his left ear and crying out in pain. I've been to the doctor and they can't see anything wrong, no infection, no temperature, he's not out of sorts otherwise. I'm not sure if the pain is inside his ear, or behind his ear. Has anyone experienced anything like this with such a young baby? It's not teething, and unlikely to be an infection....any ideas or advice would be greatly appreciated.
