I have been getting sick off and on since Christmas. My symptoms are, hot and cold, diarrhea , urge to pee a lot, nausea, sometimes headache. At Christmas time I thought I had the flu but I ended up being dehydrated and had to go to the hospital. My liver function was very high but came down to almost the range it should be but I have a fatty liver. That is all the ultrasound said but I have to follow up with her tomorrow. Do you have any idea what this could be. I can t get sick either. I get the dry heaves.
