I am 13 and my head is constantly hurting and it feels like someone is pushing against it. In the past I have had migraines and I have thrown up because of them. When I get up to do something I also get dizzy and I never feel stable on my feet. I also suffer from not enough melatonin being made in my body. I don't know what is wrong with me and if anyone could give me headaches then that would be great. Thanks, bye.
