Our ped sent us to the allergist because of all the asthma attacks she has been having lately. Thinking i could be allergy related. Allergist tested her and said no allergies. He belives she has a sinus infection called moraxella catarrhalis. He said it was spread around at daycares alot. He put her on 14 days of bactrim. I was just wondering if anyone else has had this. I have read about it some on the internet. I was just wondering if anyone knew anything about this type of sinus infection? Thanks
