Sorry to learn of your problems. I've had the ongoing mucus in the throat since I developed a stomach ulcer in 2017 (since cured) and after COVID too. I thought it was clearing up but then it got worse. My mucus is clear but definitely worse in the morning. As to blocked ears: I had open heart surgery in January and developed blocked ears during my recovery--a specialist said it was due to the big weight loss I experienced as a result of being in the hospital (I lost 25 pounds and I was not overweight to begin with so I came out very scrawny). He told me it would improve after I gained the weight back, (I'm still not back up to my pre-surgery weight), but the ear blockage has improved and now comes and goes--oddly, about a month ago I devloped a head cold and the ear blockage disappeared during that 10 day period--a short relief. However, the mucus and throat clearing remains...
