I know this is a zombie thread, but I could have written it years ago. My son was doing this. He is autistic and has ADHD and had occasional tics. A few doctors tried to tell me it was a tic, a habit, a stim, etc.
Ended up being allergies. Pretty significant environmental ones. He is basically severely allergic to everything and was having constant post nasal drip. This was uncovered during allergy testing at age 14. 3 years of allergy shots (and counting) and the cough is FINALLY GONE, once he was tapered up to a high enough allergy shot dose.
I feel bad that he suffered with that cough for over 2 years before we did something about it. It was a loud, barky, almost constant cough. He was starting to develop nodes on his vocal cords.
