I've been dealing with the thick phlegm in the back of mouth for the past 6 years I've had Covid/Long Covid. At first I was diagnosed with an ulcer. Cured that by taking famotidine but also diagnosed with GERD. Stopping chocolate helped (made me sad though). Since covid I can't stand the taste or smell of coffee (also made me sad) but that's another thing I was told to avoid as well as tomatoes. I've started eating chocolate and tomatoes again and just dealing with the phelgm. I still occasionally take famotidine which helps, but I was taking it twice a day for a few years.

Since covid, I've had a runny nose. It's clear and thin, like water. I can't go anywhere without tissues and it messes up my masks. But it's non-stop and thin and clear--drops if I don't wipe. Anyone else have this symptom?
