i just ask really as ive never vaped anything before
its not a big swelling its just very slight on the wet part of the lip i also had a tiny canker sore but that did heal up i have no drooling its not that bad thankfully
I also suspect this is an allergic reaction to something in that juice. It doesn't seem to be too serious, but if it happened to me I would be careful. Allergies can become more serious if we continue to expose ourselves to the allergen.
You could stop vaping for a bit and see if it goes away. If it doesn't it's not from vaping. If it does you have some choices.
1 - Try a juice from a different manufacturer and see how that works for you. This is quick and sometimes people who react to one juice switch and never (or rarely) have a problem again.
2 - Juice is made up of PG, VG, flavorings and nicotine (if you use nic). You can vape just VG with a bit of distilled water to thin it if required. You can vape just PG. You can vape each or a combination of them with nic, and you can add flavorings one at a time. This of course means you will be buying ingredients and mixing them yourself, but this way you will probably learn much more about exactly what affects you.
3 - See your doctor and ask for help with this issue.
I have no idea how important it is for you to vape. I smoked for 37 years and vaping was the only thing that helped me enough to allow me to quit. That was back in 2012 when vape hardware and liquids were nowhere near as good as they are today. I persevered because it was really important to me. If it's not significant for you to overcome the issue you have you could also just stop vaping. Whatever you decide, give it some thought and be careful with allergies. They can get nasty.
Best of luck with it
