My 2 year old son has been chronically congested since he was born. Specialists can't find a solution. Help!?

My 2 year old son has been chronically congested since he was born-never could use a pacifier and has never slept the whole night through:( I have been to an ENT who prescribed a nasal steroid that caused bad side effects, we have seen a doctor to take a scope of his esophagus and stomach and they found a cell that may be causing reflux, we have seen an allergist and still no reason to think that is a cause. we have gone through a swallow study...noticed nothing, a nasal scope...noticed nothing, we even removed his adenoids...nothing changed. We are currently using a reflux medicine and we haven't seen any results. We have tried the natural ways as well: saline drops, humidifier, putting him up on an incline, having him sit in a steamy bathroom, vicks on the feet and chest. Still no change. We completely avoided dairy products(and if you read labels, I feel like its in everything!), however still no progress. We will be taking him to do acupunture in hopes of a remedy. I am a mother who feels completely helpless because I can't help my baby breath. I feel frustrated that we have done surgery and still no change....not even a little:( Does anyone have any suggestions? I am searching everywhere for answers. thanks.
