Well lately I have been sick to my stomache and sometimes actuly get sick, I have also been getting real dizzy at times and have a constNt headache, no matter what I eat I'm still usually hungry it's never been like that before I also noticed I'm always thirsty and always have the need to go to the bathroom. I also have pain in the left abdominal and left bottem back area. I went to the doctor I don't know if she tested ne for anything but she said nothing was wrong. Does anyone know what this can be?
