What Causes Recurrent Headaches Along With Hot Flashes In A Child?

Hi There, My ten year old daughter has been suffering headaches over the past few months. To begin with they lasted a few days. Then after Xmas, they lasted for two weeks. She would get a break for two weeks and then the headaches would return. She has had complete eye test and blood test but all are clear. She has had her current headache for over a week and is experiencing hot flushes, which start in her face and move down her neck and stomach. Our doctor has given sinus spray, amoxocylin and calpol, nurofen but the headache won t shift. We are due to see a paeditrican in two weeks but it seems ages away. Can you help please as we are very concerned.
