Our daughter is almost 3 yrs old and was diangosed at 2 months. Since Jan. she has been having a sinus problem. Her nose will get full of mucus. After about 2 weeks she starts a cough. We keep putting her on antibiotics and within 48 hrs the sinus issue starts again. This time it was a 10 day dose and it came back on the 8th day of treatment. The clinic nurse told us to extend the antibiotics so that she doesn't get a secondary infection. We are doing therapy 2x per day and we are at a loss. We don't want to leave her on antibiotics all the time. The clinic dr. said she didn't see any polyps but we haven't seen an ENT yet.Our respirologist is at the CF conference and won't be back until next week. Any tips on how to relieve her. She is uncomfortable and I need tips on how to help her until we can talk to the head respirologist.Thanks.
