question: I have noticed a vein in my lip when i run my tongue over it. I can also notice a bump in my lip with my finger or tongue. When i stretch my lip out, i can see that vein there. I have noticed some pain with it. It is not blue or pulsing. I had jaw surgery a year ago and that area of my lip is still a little numb. I have also used chewing tobacco for about 4 years.
