My eight year old daughter has been having stomach pain for one month. Today she threw up. She's had gas, bloating, nasia and acid reflux. Can virus last this long? Any way to cure virus?

Unlikely virus. One month of abdominal symptoms is a little longer than one would expect from a virus alone. Abdominal discomfort can be from a lot of causes like constipation, stomach infection with H. Pylori, acid reflux, irritable bowel, celiac disease, or IBD. Try her on a natural organic diet rich in fiber and fluids. Also try probiotics. If not helping in a few days, see a specialist.
Call PCP. Your child's been sick for a month and you still have not called your Primary Care Physician? Please call now. Your daughter will have to be examined to be diagnosed and treatment planned.
Not virus. A virus does not last a month. There is a bacterial infection that you can get in the stomach called H pylori. This infection can cause symptoms like that. I would recommend going to a pediatric gastroenterologist. Good health.
