Hi all. I am fairly new to e-cigs although I have a little experience. I purchased a 510 and was on my way to becoming a non smoker when things started happening. To make a long story short, after two weeks of vaping away I suddenly awoke with what I describe as an electric feeling in my mouth and on my tongue. I first noticed it when I coughed. The second I coughed, the tip of my tongue and roof of my mouth started burning and felt as if I had stuck a 9v battery prong to it. That's the only way I knw how to describe it. It's like an electric burn and even after well over a week and off the e-cig, it is still going on and getting worse every day. It happens all day long. Earlier today it was so intense that I took my tongue to the roof of my mouth and kinda gave a hard swallow and it was then that I noticed that it actually burned my throat. Like I had actually swallowed something very toxic. It is doing it now as a matter of fact. I have no clue what this is. I was vaping on VG only juice and not over vaping. I was very careful with the juice, so no overfilling here either. Please can someone tell me what might have happened? It's now affecting almost all of my tongue and at times the feeling and burn is on my lips as well. I can also smell it. Don't know how to describe that either other than to say it smells like it feels. Thanks for any information you can give me on this situation. I'm almost to the point of going to the emergency room.
