Hi, I m Aileen I m 15. I don t know what is wrong with me but I would like to find out. It started yesterday, I had a fever of 99.something. I felt nauseous, dizzy, dehydrated, irritable, i was shivering, my back and my stomach hurt. Today I haven t checked my temperature but I m still a little warmer than usual. I also have a headache, and I have a blister looking thing on my face.
