It is just the pus isn't it? But never squeeze your inflammations it injures or irritates your skin and worsen the HS.. If you want to reduce it urgently due to social obligations try corticosteroid injection on it.

I have one on front of neck and one on back and it never goes away but it never gets infected either. The neck one has gone down a lot after constantly squeezing it. It doesn’t seem to fill up anymore. My husband doesn’t even have hs and he has a perpetual blackhead on side of his face.

Yes! I know exactly what you mean... I get alot of blackheads and they appear in the same area. Iv always thought of them as black heads really 🤔 but I suppose they are a bit different! Maybe the same group of beasts 😆

I have gotten a boil that had a white tip and when it burst, it was a bump that looks like the core that comes out of a Black Head.
