Chronic nasal congestion in 4 yr. old

[Lici74]

My 4 yr. old has had chronic nasal congestion for 2 years now.  We've had adenoids (adenoids) removed due to recurring sinus infections.  Shortly thereafter - snoring began w/ an obstructive sleep apnea dx.  We then has his tonsils removed (extremely large and we were told was the cause of the OSA).  Since then, snoring is gone and no sinus infections, however, his nose is constantly stuffy.  He's still having to breath through his mouth.  I had allergy testing done - positive to peanuts, cats, & dogs.  We don't have pets and I've taken everything out of the house w/ peanuts.  He tested negative for indoor and outdoor allergies.  He's been on nasonex for months and I've even tried daily zyrtec to no avail ... still stuffy.  Out of desperation, I gut out wheat, gluten, and dairy ... still stuffy.  Any ideas?  I don't know what to do or who to see next ... pediatrician?  ENT?  Allergist?  I'm at a loss and very frustrated as I feel this is affecting his quality of life.  Any advice would be greatly appreciated.

I would go to an allergist. If he already had T&A removed I assume you had an ENT do that. My daughter had a wonderful allergist who has worked with us to stop coughing and deal with congestion. the ENT for t&a dealt with my daughter as just a surgeon it seemed, and some pediatricians have dismissed constant coughing as "normal".
Keep trying a mix of meds - before her adenoids (adenoids) were removed she took benedryl, dimetap, sudafed all winter as well as nasonex, singulair and pulmacort or advair. (now she doesnt need the otc meds.) the singulair helps our family with less congestion and the inhaler (pulmacort/advair) stops the coughing.  We just tried a new inhaler and in one week the coughing returned until she switched back to the old med.
zrytec took a week to work - started the second time while on prednisone to counter act the zombie feeling, and claritin does nothing for her, just primatine works best for her dad. so keep trying various combo's with a helpful doctor.
After she was born I had to do a "candida / celiac diet" to calm my daughter - no wheat or sugar was very hard but worth a peaceful daughter. It is hard  - my daughter making noises clearing the mucous all the time caused issues with some teachers. The teachers and my daughter needed to be educated on how to deal with this as a Medical and social issue.
