Red bumps on breasts

So ever since I turned 21 a couple years ago I’ve started getting pimple like bumps on my breasts. But they have no heads to them so they’re just like lumps. Once they show up, they never go away 😞

The very first one I got, I had no idea what it was so I tried popping it and it just bled and never went away so I left it alone. Then I got another one months later. And slowly have been getting more. I CANT afford to go to a doctor. I’m hoping someone may have experienced this or knows what it is but I’m terrified and have lost SOOO much fucking confidence because of these fucking lumps

I’m trying not to cry as I type this.

They don’t hurt, but when you press on them you can feel it’s a lil bump.

Just found a new one today and almost busted out crying. Why me 😒😭

One on the bottom is new I found today 😞

The large one is the very first one I got. Still have it 1 & 1/2 years later..
