HIDRADENITIS
SUPPURATIVA
SIGNS AND
SYMPTOMS

Recurring bumps and
boils that hurt could be HS.

The bumps, boils, and sores (abscesses) of HS often come back more than once in the same area, or areas where skin meets skin, in a 6-month period. These outbreaks can flare and rupture, leaking blood and pus that may have an odor. Over time, they may connect to each other under the skin, forming deep and painful tunnels that can lead to extensive scarring.

HS is sometimes mistaken for an infection, often looking like a deep pimple or ingrown hair that can show up on different areas of the body.

TAKE THE QUIZ

Understand how HS may progress over time.

After someone sees symptoms for the first time (usually after puberty), they may keep seeing them on and off—for years. HS may be classified into 3 stages, based on how severe the signs and symptoms are. Even mild or moderate HS symptoms can have a negative impact on a person's physical and emotional health, and affect their quality of life.

Mild Symptoms

Mild

Sometimes called Hurley stage I. Typically shows up as one or multiple bumps (inflammatory nodules) and abscesses with no scarring or tunnel (sinus tract) formation.

ModerateSymptoms

Moderate

Sometimes called Hurley stage II. Typically shows up as multiple abscesses, along with limited tunnels and/or scarring.

Severe Symptoms

Severe

Sometimes called Hurley stage III. Typically shows up as multiple or extensive interconnected tunnels, abscesses, and scarring.
