About a year ago I had a white, round shaped dot on my upper
lip. It didnt hurt or something like that. By mistake, I broke it with the teeths. It looked something like this picture:

After the lip regenerated, I remained with a smal red area,not that visible, the exact same size as the dot. I believe that it may be caused by hpv, because I was diagnosed with hpv genital warts which I believe I treated ..
I have the same bump, white, on my finger.
