she needs to be taken back her pediatrition. when you mentioned the sinus infection you said a "possible" sinus infection. i am assuming it was not established 100% that she did in fact have one and if she has taken two rounds of antibiotics and both were different antibiotics i would take her bak and insist they ck for flu rsv bronchitis etc. my 4 yr old grandaughter had the same thing and when the admitting dr from the er called her regular dr to let them know he was doing an admission the first thing the pediatrician asked was if the grandmother was there meaning me. i am a nurse and they were just blowing my daughter off thinking she was overreacting due to being a first time mom. it takes abou 5 minutes to do a simple test for rsv about 10 to ck for the flu and they did none of that and she had to stay in the hospital about 10 days because they didn't bother to run the proper tests.
my child has had low grade fever and lethargy for 3 weeks. what could it be? . she has already had two different courses of antibiotics for a possible sinus infection.
