Thank you for the query.
is very unpredictable disease and every case of it is different. That is why every lower right abdominal pain
with increased body temperature and nausea
should be verified with appendicitis.
Yes it can so sold for its development (some does not have significant symptoms till the infection wont affect abdominal cavity). Moreover, it is possible that his intestinal infection could trigger appendicitis.
That is why I suggest you to visit ER once again. Physical examination should be performed (it is the most important test and can confirm appendicitis even if no indications in lab tests), abdominal ultrasound
, blood work, CRP, and urine analysis. If no findings, stool tests should be also done.
Hope this will help.
