dd(7) has had a cough for over a week. Hasn't gone like the other kids and last night kept her awake and coughing up so have an appointment at dr's for 10.30. She has just notice a bumpy rash on her leg and it is also on her lower back/bum. Looks like hives and fades under pressure but can't think of anything she may have eaten or drunk to trigger it. any ideas ?
