Re: new here
Did you re-test your son for allergies after you moved? Now that you've been there for a year, it might be a good time to have that done since his body would have "acclimated" to the new environment. There may be some local allergens that he now needs to be treated for that are different than when you lived in FL. That is what he should be receiving shots for.
I'm not familiar with the medication recommendations for treating children At my worst, I was on Allegra-D, Flonase, Astelin and Singulair. I also took additional meds when my sinuses were causing me problems. Has he had a recent CT of his sinuses?
You mention seeing an allergist. Have you been to an ENT lately?
You might want to look into nasal saline sprays or use of a neti pot to help keep the nasal passage moist and help "clean" it out as well. Again, I'm not fully sure of the use for youth, but it is a "natural" treatment.
