Yes, this can happen. With HS, cysts and abscesses can grow, merge, and eventually form hollow tunnels (called sinus tracts) beneath the skin. These tunnels can then connect to other affected areas, essentially creating new pathways under the skin.

Yes, this can happen. With HS, cysts and abscesses can grow, merge, and eventually form hollow tunnels (called sinus tracts) beneath the skin. These tunnels can then connect to other affected areas, essentially creating new pathways under the skin.
Here's how it tends to progress:
- A nodule or cyst forms under the skin
- It can grow into a painful, pus-filled abscess
- When abscesses repeatedly heal and reopen, tunnels can form between them
- Those tunnels can spread and connect, creating new tracts One myHSteam member described it well: "Does anyone get a bump or tunnel that never heals and just refills with fluid? It's not really painful, but it's irritating because it leaks when it wants without warning."
The tunnels can fill with fluid, pus, or blood, and if they reach the skin's surface, they may leak and cause odor. Over time, they can also create scar tissue that limits movement, especially near joints.
The key takeaway here is that catching things early really matters. Reaching out to a dermatologist when new bumps appear or pain increases can help stop tunnels from forming in the first place.
