Well i switched to e cigs about 2 months ago and was doing really well staying off analogs. I started with pg only e juice then the second month i started using Kentucky applewood from vermillion river pg and vg. About three days ago i started getting a pain in my right side off my face where your sinus cavity is. thought nothing off it just seasonal sinus stuff. well yesterday i woke up to this huge growth under my nose in my gum line. with nothing but pain. i started panicking thinking of all the possibility it could be and all the changes i have made. i was thinking it was my ecig going what the hell have i been vaping what am i allergic to. Today i woke up and more swelling lip was swelling now. So i went to the doctor scared and they told me i had a absessed tooth and to go to the dentist. didnt even think about that until the doc told me. I had a crown put on the tooth just below the growth so went to the dentist and had it taken care of. the problem was it did not set properly. Well i had a laugh about it and im vaping my apple wood now. I just wanted to say if you have a problem go to the doc first before you blame a ecig because i believe ecig are no more dangerous than smoking analogs or getting drunk or anything else that is pleasurable that we over use
