How to deal with something on the skin T_T

I have dry skin that doesn't usually break out, but sometimes I do get some.

Just last night before going to bed, I suddenly felt a sharp, stinging pain under my eyes and next to my nose...? Out of the blue, and when I looked in the mirror this morning, I saw something raised up—it's red. It doesn't feel like sebum, but the redness and bumps keep bothering me.

How do you treat breakouts on your face?

I heard that getting an injection at a dermatologist works wonders, but I want to learn some self-treatment methods at home!

Or, since I'm the type of person who can't stand it and always ends up tearing it apart, drawing blood, and leaving a scar ㅠㅠ lol, I need some advice. Should I just leave it alone...?
