I've had this bump for months now, it's been bothering me because i do not know what it is. It's a little lighter than the color of my lip and i can't feel it if i try, only can see in a very lit room and looking into a mirror such as a bathroom. It doesn't hurt or tingle, i think it tingled months ago about in april but, I'm not to sure if it was on that side. I have four wisdom teeth in my mouth that I have to get taken out when I get the money, and I often leave my lips chapped when I wake up or am in the house. Not sure if the problems i informed you on are possibly the causes but I would like to know. Lastly on my checkup i went to thhe doctors and had them look at it the side it's probably benign but couldn't put a name to it. If you know of anything to put my constant worry at ease I would appreciate it
