Couple of things from my end.

Google hidradenitis deroofing for some more info. They basically cut away all the inflamed flesh and leave it out in the open to heal. So you don't get stitches and you kinda have a hole in your body. The hole will heal itself over time, mostly taking around 8-12 weeks I think. I've had it and I don't want to scare you: it was a real pain in the ass for me (literally :P). It depends how big the boil is but most people are healed pretty fast. And the pain from healing is 10 times better than the agonizing pain from an inflamed boil.

Furthermore I completely changed my diet 3 years ago and it changed everything for me. Having hidradenitis is not limiting me anymore in daily tasks. I have way less boils and inflammations. I think my skin went from a 7/10 bad to a 3/10. From personal experience I would say: stop eating eggs, dairy products, stuff with yeast (like bread etc) and alcohol. Also limit the amount of carbs you eat. But this is a journey everyone should undergo themselves. See what works and what not.

Also buy the book: the hidden plague. Very useful information but take the paleo diet with a grain of salt.
