Took DD2 to see our GP this afternoon.
She has so much cattarh (sp) in her ears that her ear drums are opaque (should be translucent).
The inside of her nose is infected, hence the massive nosebleed last week.
So we are back on the mega antibiotics.
The cattarh could be causing hearing problems which may then be contributing to the behaviour issues. It is possible it is a type of glue ear, but that can't be diagnosed fully until she has had the antibiotics and the doctor sees her again to check if the cattarh is still there. So for now, who knows.
