[|Human|] my son is 9 years old and he was hospitalized yesterday.  He has been vomiting non-stop for about 3 days, complains of abdominal pain in the belly button area, no diarreah, and throws up everything even water.  He was given medication for the nausea and he is still vomiting.   Can a stomach virus cause that?  he has always been a healthy child.
[|AI|]  Hi. The stomach virus is said to have caused this if all the relevant investigations are normal. You have to get the following investigations : Ultrasonography of the abdomen to see for appendicitis, lymph nodes are very common at this age-group. Complete blood, urine and stool tests. Continue with the medications along with antibiotics as per the reports. This may take a few more days to get settled.
