Are there any treatments or care options for chin acne?

At first, I thought I was just getting one or two due to my period or fatigue, but now my entire chin is red and bumpy, and I'm getting huge bumps that are hard and painful from the inside when I touch them. They don't pop well, so if I leave them alone, they just leave dark discoloration. Even if I try to cover them up with makeup, the bumps show through, so I get incredibly stressed every time I look in the mirror.

I change my pillowcase frequently and wash my face thoroughly, but I really don't know what the problem is. I've heard that chin acne can appear if your uterus or stomach is unhealthy; could it really be an internal issue? At this point, should I visit a dermatologist for extractions or medication, or are there ways to fix it in my daily life? Please give me some advice.
