What Causes Headaches And Nausea In A Child?

Hello, I am Laretta Patel and I m asking on behalf of my 13 year old daughter. Please, all help will be much appreciated. Basically, she is suffering from headaches. However it is quite strange. She only gets these headaches when she has a sort of de ja vu experience, as if she had already done the things she was doing at that moment, she explained its like a memory of doing it is triggered, causing her to have a de ja vu experience. After this has happened, she feels terrible headaches, a feeling like her insides are burning, and often the feeling that she may vommit. She has been having this happen to her, on average, once a week, for the past 6 months-ish. Please can you tell me if anything is wrong with her, if so shall I take her to the doctors, and is it treatable? Thank you very much, we are so grateful Mrs Patel
