What do I do about my abdominal pain? I have had vomiting, nausea, and have to use the restroom ever time I eat. I have green stool and I went to the doctor and he said I have a virus and it will probably last up to 3-5 days. It's been longer than a week

You . You should go back and see your doctor. Most viruses tend to clear up in 7-10 days and when they don't, often we do further testing. You doctor may want to do stool studies to check for blood, fat, bacteria, or parasites to look for other causes of your continuing nausea, vomiting and diarrhea. Your weight loss and weakness are concerning, so don't hesitate to call your doctor. Good luck!
