Dear Flores, it is not so usual but is possible to have the appendicitis
at this age. Many diagnoses such as mesenterial adenitis
, invagination or ileus can be considered, but I doubt because he has a mild clinical presentation. Fever is a sign of any infection in the body,and tummy can hurt related to pharyngitis
or viral infection, respiratory or urinary infection... Did they check his urine? If he doesnt have symptoms now and no fever then you should just observe him and look for signs such as blood in the stool and urine, weight loss
, or sharp abdominal pain
with fever. It it happens go to hospital immediately.
Wish you good health, Dr. Ivan Romic (Rominho)
