You mention a number of different symptoms, which may not all be related to each other. It is important to discuss your concerns with his regular pediatrician
, as that is the doctor
who knows him best and will best be able to answer your questions.
For example, his platelet count is a little elevated and it sounds like his chest x-ray is a bit abnormal. This might indicate that he has an acute infection, such as a bronchitis
or pneumonia, which might need to be treated with antibiotics (if it is severe), or potentially just observed (if caused by a virus and not very severe).
On the other hand, it sounds like the persistent dry cough, sneezing, and snoring are potentially a separate issue which have been going on for quite a bit longer. These might be signs of an allergic condition, such as chronic nasal allergies, which could cause these symptoms. Alternatively, they may be a sign that his adenoids have enlarged again, or that his tonsils are enlarging into his airway (if he did not have his tonsils removed when he had his adenoid surgery).
I would start by discussing your concerns with his pediatrician at your earliest convenience.
