From your description, I think your son has a tic.
A pediatric neurologist should be able to diagnose this and advise you.
Here is an article written by a mother of a child with this problem:

Hi,
There are several causes of the symptoms you describe that your son is having - this could be secondary to post nasal drip seen in acses of sinusitis, rhinitis and asthma; this could be due to GERD; tonsillitis or rarely - out of habit.
Since when is he having these symptoms? Does he have any associated symptoms of cough, breathlessness, wheezing, post nasal drip, fever , etc?
Is he on any medications currently? Has a CT scan of his sinuses been done? Is he allergic to any specific substances? Have he had allergic reactions in the past?
You could give him oral antihistamine medications like cetrizine or loratadine and see if it helps with his symptoms. Also try steam inhalation, warm saline gargles and saline nasal drops several times a day.
If his symptoms still persist, you should consult a doctor because then he would need to get certain investigations done and would probably need steroid nasal sprays and a course of antibiotics.
Let us know about any other doubts taht you have and post us on how he is doing.
Regards.
