Forgive me the length of this post.
Some background. My 11-year old son has had an ongoing cough for about 3 weeks. It started with a runny/stuffy nose. I thought it was a cold, but it seemed to come and go. I assumed it was general seasonal allergies, which are terrible in this area. He's never seemed to have a big problem with seasonal allergies in the past other than some occasional sniffles. However, the pollen has been extreme in our area this season. It's non-stop. You can see it all over everything. He doesn't get itchy or puffy eyes. Just on and off stuffiness and drippiness. I've given him Zyrtec and Flonase.
At one point, the drippiness and stuffiness were somewhat bad (again, I can't swear if it were a cold or allergies, although it did seem more like allergies). During that time he started coughing, which I attributed to post nasal drip. However, after a couple of weeks he was still coughing periodically. It wasn't a hard or painful cough. No wheezing. He felt like it was a tickle, but he wasn't totally sure. Last week I took him to the doctor, who felt that given how long it had been going on he would put him on a Z-pak, although his lungs seemed clear. I'm not one to rush into antibiotics, but since he hadn't been on any antibiotics for at least the last couple of years, I went with it.
He finished the antibiotics on Monday. Today, he is still coughing. It's not constant, but it is periodic throughout the day. He's not having fits. It's "cough, cough", or "cough, cough, cough" and then nothing. It's just, kind of there. I'd have thought it would be gone right now. I suppose it could be some remaining irritation. It could be some more allergy issues (I'm personally occasionally having mild issues and once in a while coughs that seem pollen related). But I'm not sure.
I'm wondering if this could be cough-variant asthma. Does anyone know what cough-variant asthma sounds like? Is it more constant, or does it come in larger fits?
I should say that he's sleeping through the night. A little over a week ago, it kept him up a bit one night, but that was the only the one time.
He seems to think it's better than it was.
