What Are Lip Warts Called My 3.5 Y/o Looks Like He's Getting Warts On His Upper Lip. Could It Be? ?

My 3.5 y/o looks like he's getting warts on his upper lip. Could it be? ? - what are lip warts called

He had warts on the hands for over a year. We took him there, the doc 5 months, but his pediatrician said that removing it was a bad idea because it can cause scars and can not work. He sucked his thumb at the moment, and we hold it for her, but she said she would not be a problem. We returned a month ago, because he now has 10-15 warts (mostly small) hands. We started with a warts-counter (which is not operational) and the so-called Bite Stop to thumb sucking, which works.
Weeellllll now has the color of several small bumps on the edge of the upper lip. I will not be able to make an appointment until tomorrow.

What should I do? "
