I had to chuckle when I saw this word. It looks for all the world like a type of Japanese food. But when I saw the definition, the spelling made sense, with the "rh" prefix, like "rhinitis."
Bronchitis frequently causes wheezing, or rhonchi, also, and this, along with a slight cough, can persist long after the person has recovered. So it’s not always a symptom – sometimes, it can be an after effect.
But as the article mentions, any kind of wheezing that lasts longer than a couple of days should be checked out by a doctor. It's not something to ignore.
