Suggest Treatment For Recurring Bronchitis,sinusitis And Sore Throat

I suffer from recurring bronchitis, sinusitis, and as a kid would often get steep throat. I am 29 and now am suffering from an enlarged R tonsil, sore throat on just the right side and painful, swollen glands on the R side under my jaw and near vocal chords. I always have drainage in the back of my throat.Could my tonsils be the blame for the recurring problems? If they were removed, could it potentially help the sinusitis and bronchitis? OH, also I have had problems with being able to smell anything for years.
