My 11 year old son has white mucus back up in his nose. His adenoids were removed last year and that seemed to help for a short period of time. Now that allergy season is here it is becoming very bad. He takes medicine for potential acid reflux which the ENT thinks could be causing mucus build up along with Claritan and saline spray every day. He does not have a sinus infection but his breath is beginning to smell. I also had him allergy tested last year and everything came back normal except for seasonal allergy effects. He gets frequent fluid build up in his ear that causes him to try and pop them regularly. I have been to the ENT several times in the last 6 months and feel like nothing helps. Any feedback from those experiencing similar issues would be much appreciated.
