Geezy peezy Lori so sorry to hear about that experience.
When I discussed vaping with my Allergist and the problems/reactions I had early on to PG liquids he very calmly walked over to the computer and printed out a case study on allergic reactions to PG in anesthesia patients and handed it to me. As an Allergist, he said allergic reactions to products containing PG are seen a lot in the practice and it's far from being an uncommon problem.
He has no problems with vaping. But an allergic reaction to a PG base vaping liquid? Didn't surprise him at all.
And before anyone starts freaking out and getting all hysterical - no, this isn't a problem for the majority of vapers. But there is potential for an allergic reaction. If you think that's what is going on it's easy enough to do a reality check. STOP vaping the PG base liquid and see if the symptoms go away - usually in short order. Switch to a 100 VG based liquid and see if the symptoms stay away. And of course, should a reaction be as severe as Lori's get medical intervention.
For me: The first four days of vaping I kept getting nauseous. Every so often I would get a burst of itchiness on my hands. (Ever had an allergen "grid test" done on your skin and got a strong reaction to something? It was like that.) But on day four, after only a half dozen hits off my PV, WHAM! Nausea, vomiting, intense itching on my hands and forearms, and difficulty breathing. It felt like my lungs were lined with wet cheesecloth. The breathing weirdness was probably the scariest part. It wasn't scary enough for me to call 911 - but I thought about it...
I put down the PV and the symptoms slowly dissipated over the next three hours. I didn't touch it again for three days.
After I got my nerve back I researched the issue on ECF and after I got my balls back I cautiously proceeded to try my 100 VG base liquid and... no problems. No problems ever since.
Unfortunately Lori you could be one of the few who even has a reaction to the small relative amount of PG in flavorings. If that is the case it really narrows down your options. Check in with Annette at Virgin Vapors as I think she has a line with some completely 100 VG liquids.
And there are reports on ECF from people who have an allergic reaction to a specific ingredient in a flavoring itself - not necessarily to the PG or VG used in the flavoring.
This issue is why I suggest any newb should only get sample sizes in their first order, half of them most likely in high PG base and the other half in 100 VG base. It's hard enough for anyone new to this to figure out the right nicotine level and flavors. And should anyone have an allergy issue with either PG or VG it may rear up sooner (like me) rather than later. No point in spending piles on a boat load of liquids in that first order, should you come to find you cannot vape most of what you purchased if an allergic reaction pops up.
If this is a real issue for you get this in your medical records and mention it again - like twenty times - before any surgical procedure. PG is used in a lot of aerosol anesthesia. A test can be done prior to surgery to check for an allergic reaction and arrangements made to use a non PG based alternative.
