Yeah hopefully it's just one cyst like Lucca said, if you get that taken care of you may not get more, or at least not very often. I have family members who occasionally get one cyst that goes away on its own or after getting it lanced. I know it sucks having to go get it lanced by a doctor but they can really get all of the bad ->-bleeped-<- out of there much better than you can by squeezing it, which makes it much more likely to improve
My HS is pretty bad and I've had 6-7 surgeries for it and tried just about every drug or natural remedy, completely changed my diet, etc. Diet helped a little bit but the only thing that ever helped me a lot were immunosuppressant drugs like humira, prednisone, remicade, etc. It may seem like a condition of the skin/hair follicles but ultimately the root cause is autoimmune related. The immunosupressants just carry a lot of risks since your body is less able to fight other illnesses or infections, so I wouldn't resort to them unless your condition is really bad.
Good luck at the doctor!
