hi everyone, so i jut started vaping about a month ago, i had actually quit smoking cigarettes 6 years prior and bought the kit for my wife who still smokes, long story short i demoed the PV to many people and really enjoyed it, so i kept at it, and love it, tonight as i just finished dinner i felt a bump towards the back of my mouth just past the molars...it is new so i looked in the mirror and it is a perfectly round bump, looks to be filled with liquid, i know there is a salivary gland located there so i am assuming it is a **blocked salivary gland**, my question is has anyone else experienced this sort of thing from vaping? I am vaping quite often, especially today, i always drink lots of water but still get really dry mouth, and now i notice this bump....kind of freaky
