I had Covid last June, followed by months of the terrible hacking cough others have mentioned. The cough eventually receded, but I was constantly clearing my throat before I could talk & my voice had become chronically “raspy.” My primary care doctor referred me to an ENT who recommended Musinex. I take 2 capsules morning & night, & it has definitely helped. He also referred me to an imaging center for a “barium swallow” test, which involved drinking multiple cupfuls of this milky liquid while images were taken of the stuff passing through my esophagus. I was later told I have a “Zenker’s diverticulum” ( it’s really a thing—I looked it up!). It’s a little pouch-like protrusion into the esophagus (I presume caused by all the coughing). It collects mucus, also food particles, and can cause gagging & choking, as well as the chronic throat clearing. The ENT thinks it’s not serious enough for surgery (of course, he isn’t living with it), & I’ve only had one instance of serious choking, so far. That made me more conscientious about taking the Musinex, which definitely helps. I see my primary care physician later this month, & I’ll talk with her about what, if anything, to do next.
