I wouldn't attribute it to
vaping if it is Bells. However, I'm not a doctor, so take it with a grain of salt. Having said that, it appears one of the main common traits that causes/shares with Bells, is Herpes simplex A. So I wouldn't pray that it's that just yet either. It could also be a temporary onset, I've heard of that before from someone who sat in the direct output of an air conditioner as well so.. who knows.
Get all the possibilities of what it is first before you attribute it to
vaping, however, in the chance that you are having some form of reaction to something in it.. I also would try to
vape as little as possible till you see the doctor, if at all.
Also, yes.. if you can get to the ER, I'd go if I were you.
