I'm just getting over a cold, which is every bit as annoying in my nose, sinuses, and throat as any cold ever was, BUT, it did not affect my lungs AT ALL -- and this is the first time THAT has happened in 40 yrs.
Here's a tip, though -- for anyone who usually vapes very-high-PG, as I do... you might want to ease up on the PG just a little, if you catch a cold; I was vaping 90% PG when I first got the cold, and within a couple days, my throat was bright red and very painful, and my nasal passages and sinuses also felt completely raw -- and now my nose and throat feel "crusted" in the immediate aftermath. The high PG doesn't bother me a bit when I'm well, but with a cold going on, the irritation was horrible, and the nasal passages so raw and then crusted, a lot of nosebleeds, everytime I have to blow my nose -- which of course is quite often with a cold. I eased back down to 80% PG, and it started feeling a little better. Now back to 85% PG, and just wishing all the stuff that came WITH the cold would hurry up and vacate! Still, 2 wks for a cold to run its full course beats the hell out of cold+6 wks of coughing-up.
