I have been experiencing mild headaches, dizziness, upset stomach, feeling nausea and nose bleeds. I feel dizzy when turning my head left or right or unstable at times. I also get a metallic taste in my mouth at times and swollen neck glands. I feel constantly tired and I've been feeling like this (on and off) since April 2012. I've had a few blood test because my doctor thought it was glandular fever, liver failure but it seems I don't have a satisfied answer, except viral flu
