stage 1 is like a boil every other month or longer
stage 2 is more frequent boils with the beginning of tunnles
stage 3 is evenore frequent boils with tunnles
i think there are only 3 stages officially but i feel there should be 4 cuz i have frequent boils and tunnles and tunnles that interact other tunnles as well as scar tissue constricting nerves, but this is the basic run down. i would also talk you my derm about what stage they think you are based on how it looks.
Me too.
Look on this site at the resources articles. They are great information regarding HS.
Finally seeing one tomorrow just moved to a new city.
I'm sure a dermatologist can tell you.
