Hello, I am a 26 year old female and I ve had a small bump on my lip for about 6 months. It has not grown in size since noticing it and it lays underneath the skin. It appears to be a black color. No pain, no blistering, no other symptoms. I usually never notice it, but it eventually gets irritated maybe and pops out as a bump. So, most of the time it lays flat inside my lip, but eventually pops out forming a bump. I can also push it back in. I ve tried to diagnose myself by looking at pictures.... from Venous Lakes, and blood blisters, to lip cancers. Either way, I do not believe it will go away on its own. As an added note, I do often rip the skin off of my bottom lips when I am nervous, I try to stop. Not sure if it s trauma related due to me biting or chewing on the lip. Thank you.
