How should I help my daughter's illness?

My daughter has been sick with a bad cough since Thursday. On Saturday, her pediatrician diagnosed her cough as asthma related (because it runs in the family & its her 2nd time in less than 1 mnth w/similar trbl) . He prescribed symbicort inhaler. Sunday, my daughter woke up with fever 102 degrees. Pediatrician advised to take her to ER. Doctor in ER took xrays. He said she had a little inflammation in her bronchial area of lungs & he agreed with pediatrician asthma related & continue inhaler, take robitussin dm, & tylenol. Also her pulsox on Sat. was 95 & on Sunday 96. Today she's still coughing all the time. still has fever, and she is very pale. I'm so frustrated with the dr's not helping her. She has a recheck appointment scheduled for Friday, should I wait til then or should I take her back today?
