It’s funny how I thought this was strange when I started feeling that, but now I’m realizing it’s not just me. Guess it’s part of having HS.

Omg yes! It feels like something's crawling beneath the skin and eventually the mass itch starts but the odd time not but I know there's something brewing in there.

Yes I have. It itches very much and like you described it feels something like tiny ants under my skin
