Hello my name is Abigail. I'm 13 going on 14. For a little over two months I've been getting headaches that are from my right to left temple. With those I sometimes get nauseous. I was doing a morning workout and I'm now nauseous. I've been getting nauseous nearly every morning, after I eat, and throughout my day. One of my older friends said it could a blood problem. I looked up symptoms of a brain tumor and I have about 5 of those. I had a concussion when I was 7 and ever since then I've lived with headaches. Two months ago they have gotten worse. Can someone PLEASE tell me what this may be. My mom won't take me to the hospital for help so I want to gather possibilities and facts to persuade her to take me. Please help, thank you -Abigail hicks
