A zit ON the lip - not the edge? - sh.itjust.works

I found a lump on my lip the other day. Like literally on the lip-lip. Not the edge where I’ve had them happen before. I’ve NEVER had that happen. A zit ON the lip which I squeezed a yellow lump out of. How does that happen? AFAIK the lip doesn’t have pores? It’s a mucus membrane? That’s like getting a zit on your eye ball… How? Am I going to die? Has anyone else had this? Don’t tell me to see a doctor about a lip zit!
