What To Do For Asthma And Sinus Infection In Child?

My daughter is 7 years old, 4ft1in and 70 lbs. She has had respiratory issues since she was 6 months old. At age 3 she was diagnosed with asthma and was on a daily pulmicort treatment administered via nebulizer. Over the last 2 years her symtoms have appeared more allergy related and less asthma-like. We have gone to the doctor numerous times and she has had several sinus infections, and quite a few ear infections. She s had numerous doses of antibiotic for the sinus infections and the last one she had was treated for 21 days. We saw an allergist who tested her for common allergies found outside and in the home. She tested neg for allergies so he referred us to an ENT. We visited with the ENT and he suggested having her adenoids removed, which I agree with. In the meantime, she coughs like she has a cold but doesn t feel bad and there s still some sneezing and stuffiness. She also gets hoarse at times or at least a noticeable change in the sound of her voice. Could these issues be result of problematic adenoids? Could it be that I need to get a second opinion on her allergies? I do believe the surgery will help but even after numerous dr visits, I am not sure this is the only source of her issues.
