I had Covid about a month ago, my first.  My nose has been running like crazy all day from my first snuff until bed time. I then use a net pot and sleep like a baby.  It doesn’t burn but my wife is fed up with me snorting all day, that just sends snuff down my throat and I end up coughing.  I tried stopping but when you work with it all day that is very hard.  Funnily enough, my wife was a way last weekend and I opened all the doors and had a cigar.  My nose dried up!  I have been a lot better since.  Still runs but not as bad.
