Good evening, my daughter has adenoids of 2-3 degrees. I've already gotten tired of drops for two months with no results plus an otitis externa in both my child and son. We have been treating it for a long time, but nothing works normally. There are children with green phlegm who go out and nothing happens, while my adenoids cause otitis ? there are some folk remedies like oils that you should do something about, it's sad for children.
