Hello, I am a sixteen year old female. For the last three years I have been feeling really tired all the time. I sleep about ten hours a night. I seem to always have headaches and dizzyness. Sometimes I feel out of breath and I get hot flashes. My head feels really hot and my body feels very cold. I also get random cramps all over my body. I used to get random chest aches and panic attacks, but they have become less frequent. I have seen a cardiologist and he said my heart is fine. Also i don t have diabetes and my blood tests come back normal. I did have problems with dehydration a couple of years ago but since then i feel like i drink alot of water. I m just starting to get conserned because the fuzzy-ness in my head doesn t go away with Advil and the cramps in my stomach and muscles cause me alot of pain. I tend to eat pretty healthy, I don t eat alot of candy, fastfood, chips, or sugary foods. I eat a decent amount of vegetables and fruit everyday. I haven t had sex, smoked, done drugs, or drink alcohol. I don t know what is wrong with me. Could i be allergic to something, or have eye-sight problems? someone else mentioned inner ear problems? I don t know what else to do.
