I used to have the same problem! They are the cystic ones. Trust me, the only thing you can really do is wait it out. Don't try and pop it yourself, because it will just get worse and worse (and it will hurt and be red), and often if it's popped then it can lead to scarring. Just keep using your regular routine, and try putting some benzoyl peroxide or whatever on-the-spot pimple remover you have.
Oh, and DON'T use toothpaste! I tried it, and while it got out some of the stuff, it ripped open my skin a little so I had a scab instead.
Oh, and you can also try icing it, which I found helpful, as it seems to bring down any sort of swelling.
Sorry this is a little gross to talk about, but yeah. Anyways, good luck!
