The line in the middle of my tongue is slightly deeper and looks wider since vaping.. why is this? I also have developed a slight ulcer in the back of my mouth (near the tonsil area) that's sore but otherwise doesn't seem to be getting worse. Is it due to nicotine making contact with my tongue? Has anyone else ever experienced something like this before?
I haven't kissed or done anything else with anyone in MONTHS (been too busy with work to bother with relationships right now). I had a full STD check after my last partner and I'm free and clear. It isn't that at all; I know without a doubt.
