Wow this sounds exactly like me. So glad I found this. I got Covid 5/31. Tests were negative but my doc is convinced it was Covid. 7 weeks later, post nasal drip, glue like mucus in the back of my throat, ears popping and crackling and nothing is helping! It’s better but not resolved. Happy to hear others have had this experience. I guess I’ll keep waiting it out. I drink hot honey water, try to clear it as it comes up, suck on cough drops… tried Flonase for a month, Claritin-D, two rounds of antibiotics, nasal wash. Nothing takes it away completely. Ugh.
