The most common staging system for HS is what's called the Hurley staging system.
In Hurley stage 1 disease, that's where mostly there are just abscesses and nodules that come and go, and the skin can generally return to normal as those lesions resolve.

Once you get to Hurley stage 2 disease, that's where you start to see tunnels or sinus tracks that develop – some people refer to them as fistulas. These are areas where there is scar and a pocket, or a tunnel, that exists under the skin that stays there over a longer period of time and becomes recurrently inflamed. If you have just one, or a very limited amount of area involved by those types of lesions, that's considered early stage, too. Once that becomes widespread and interconnected, that's where it becomes Hurley stage 3 disease. 

That staging system is mostly designed to help figure out how much patients need potential surgical intervention over time. It's not a great system that changes over time with response to medicines. It helps to understand maybe what's necessary for treatment in the long run for those patients, though.
