It's embarrassing, but see a dermatologist. It's definitely HS and it will not get better.

All excellent answers but the blood is always there before or after you get flares. Your best ideal that I done was if they flared on me and I had no plans to go anywhere, (Gonna tell on myself, but it really helped and eased up pain, throbbing, and so on), I would wear no bra, no underwear, and since I only live with my husband, I'd wear a big size shirt or something and not have it being touched by anything. I also would alternate heat and ice with the cream and powder my Dr wrote me out for it. So, just a few things that I done and I can actually say I very seldom get one flared up but my Dr did tell me that I was supposed to pull them out and see what I get, not to squeeze them because some may think you conquered it but sometimes it bust under the skin and your gonna have it longer if it bust under skin. So a little bit of info pull apart and not smash or squeeze. GOOD LUCK AND I WILL HAVE ALL IN MY PRAYERS 💕🙏😀

Yeah, the majority of my flares fill with blood rather than pus.

Yes mine do that sometimes too

Sounds like it could.be. You might wanna ask you primary care to send you to a dermatologist to confirm
