is my pediatrician wrong about my 4 yr old's fever? my 4yr old son began complaining of stomach pain late Wednesday morning.  When he woke up from his nap in the afternoon he had fever of 102 degrees, headache & vomitted.  He refused food. We had to force him to drink.  We gave him ibuprofen.The fever continued through Friday reaching a high of 103.8.  He was seen by his pediatrician Friday morning.  My son was diagnosed with an "adenoid virus".  The doctor said fever would continue a couple more days.  Friday afternoon my son ate a little bit, but then had a bout of diarrhea.  Saturday morning he woke up with swollen glands.  Today, Sunday, his fever continues (todays high was 101.6) He's still not eating well.  i am concerned the pediatrician may have misdiagnosed my son.  Should i take him back to the pediatrician tomorrow or wait a few more days

Summarized question: When should we go back to the pediatrician if the fever and diarrhea caused by adenovirus continue?
