I have severe hydradenitis, mainly in my groin area. It is a nasty condition, I have suffered with this for 13 years and as yet have still to find a treatment that helps.
Trasnslated, the name basically means erupting boils and as it is classed as an orphan disease very little money is directed towards reasearch
If this condition is suspected then the first course of action is usually long term anti-biotics. Generally beginning with erythromicin moving through the scale to roacutane. These are usually prescribed for 12 month periods. Along with this the contraceptive pill may be given, one containing anti androgens.
Ask for a referal to a dermatolagist, s/he will diagnose you. What you have sounds like cysts but i could be wrong. I currently have 3, which is my norm one of them is the about 3 inches in size.
For me it's a pain in the ass (literally sometimes lol) but i live with it and get on with things as best i can.
God, I read back what i have written. I'm sorry if i scared you, as i said at the beggining, mine is severe. And i have had it a long time, what you have does not sound like boils, but cysts.
Thanks for listening, and sorry for rambling on
