DD (6) has woken up saying she's in a lot of pain, it's just under her left ear. It's really swollen compared to the other side and you can feel a sort of lump when you run a finger over it. She doesn't feel unwell apart from this pain and doesn't seem to have a temperature. Anyone have any idea what it could be? Obviously can't get a gp appointment today so just hoping it's something that will not get any worse over the day!
