I’ve tried nasal rinses. It tends to plug my ears. I used the saline spray in a can. Works for a bit then back to yuck again. Did your issue ever go away?

First contracted Covid 19 in January 2020 from students returning to Canadian classrooms from China and Filipines. Continued congestion with recurrent Covid infection and after receiving the mandatory covid vaccines. Since the first infection until now, 3 years later, I have been plagued with a sticky clear phlegm. Initially it was much thicker and seemed to have properties of super glue, almost adhering my fingers together, and being very difficult to expell. Taking over the counter mucus relief pill 2 times daily relieves coughing but mucus continues to be with me now whereas prior to Covid infections and vaccines characteristics of my mucus were much different, even during 3 separate bouts of pnuemonia. When students use stink bombs at school, I notice odors of suphur are trapped within this mucus in my sinuses, leaving me exposed to chronic odors with associative discomfortfor days. This was never expereinced prior to Covid 19.

Best to ask your own dentist about adding lemon juice to water as I recently did. I believe any benefit of using lemon juice may depend on the condition of your gums.
