Is there something known about PG that can cause these kind of problems. Like red skin allergies etc?
I don't think I've heard of your specific reaction but allergic reactions to PG are known to happen. And in allergies, specific reactions vary widely among people. I believe you said you had no problem exhaling through your nose but that would mean vapor is coming into contact with your nose on the exhale. You know, drifting around the nose after exiting, such things.
Or could be a contact allergy. You had some amount of juice on your fingers and scratched your nose.
Heh, I never went into health care but I'm about the only hold out in my family. One thing I learned quite a while back is people touch their faces an unbelievable number of times per day. I mean huge numbers up in the hundreds and higher. We're rarely conscious of it. It's one reason frequent hand washing is being pushed harder to stop the spread of infectious diseases. We're simply not conscious of the huge number of times we touch our faces and expose ourselves to whatever is on our hands at the time.
But then that could be the nicotine (which can irritate the skin even in low concentrations) or a PG contact allergic reaction.
Or... you touched something completely else that had nothing at all to do with vaping and rubbed or scratched your nose.
Or... funniest one that happened to me was having a "sun burn like" rash on one side of the back of my neck and being completely mystified what the heck was going on. Spent days (off and on, not non-stop, I'm not that obsessive

), speculating on what I could have come into contact with only to realize, finally, my confusion was sticking the "like" part at the end up there. It
was a sunburn.
Ran into somebody in the grocery store parking lot and talked a while. A longer while than I realized at the time. And it was, you know, summer. There was this big ball of light in the sky and one side of my neck was turned toward it most of the time.
(Talk about a d'oh Homer moment when I thought of that)
My family has a big time predisposition to allergies so I'm always having some reaction to something sometime. I've gotten to where I ignore it most times. Mine aren't as bad as some and much of it can be shrugged off. But I can tell you this much, trying to figure out the source of a reaction is a pain in the keester. There are so many variables.
But try some all VG liquids. See how that goes. I haven't tried MBV's versions myself (I get 50/50 from them most times). I do like several of the Johnson Creek "Red Oak" line which has no PG. You can order little sample bottles here:

It's also possible, in my experience, to have some oddball reactions when you first get going with vaping but they go away. My sinuses went bonkers a few weeks in then settled down. Though, sometimes, the first exhale of a VG only liquid can make me sneeze like pollen does. But just the first time. And not always. I suspect it's when the pollen count is high anyway and the VG (being a vegetable glycerin) gets in there and mingles, something happens to trigger a mild reaction. I dunno. It's rare. Doesn't persist. Doesn't happen all the time. So I shrug it off.
So many allergies run amok in my family, if I spent much time thinking about them, I'd go crazy (some claim this has already occurred but don't listen to them, the voices in my head say they're the crazy ones!). I may or may not have had a reaction to vapor at first for a while--or the pollen count went through the roof, who knows--but kept going and it went away.
One way they do deal with allergies is repeat exposure to "desensitize" you. That's another thought to add to an already confusing mix.
Have I confused you enough yet?
See, this is why I didn't like biology and didn't end up in health care like just about everybody else in the family. It's messy and confusing and complicated. It makes calculus and crazy, abstract quantum physics look simple and straightforward. Heh, if people ever really knew how much their doctor was guessing, they'd freak. I mean, expert, educated guessing is better than ordinary guessing but there's a lotta guessing going on in health care. We understand the origins of the universe better than all that gooshy stuff inside ourselves.
