Quick orientation

Hidradenitis suppurativa symptoms involve more than a list of individual
skin changes. What matters is the combination of:

1. type of lesion,
2. body site,
3. recurrence or chronic course,
4. burden from pain, drainage, restricted movement or embarrassment.

The symptom pattern matters

Hidradenitis suppurativa is not defined by a single symptom. What matters is the combination of typical lesions, typical body sites and recurrence.

Symptoms that are frequently reported

Deep painful nodules

They often sit deeper than a superficial pimple and can cause pressure, throbbing or strong tenderness on touch.

Abscesses and weeping lesions

Inflamed lesions can open and release discharge. This can significantly affect wound care, clothing, concerns about odour and everyday life.

Sinus tracts or tunnels

With longer-standing disease, channels can form under the skin that connect inflamed areas or repeatedly weep.

Scars and hardened areas

Recurrent inflammation can leave behind scar tissue, cord-like indurations or restricted movement.

Pain and loss of function

Pain is a central symptom. In the armpits, lifting the arm can become difficult; in the groin or buttocks, walking and sitting can be a burden.

Describing symptoms over time

A single finding on one particular day can shorten the story.
For the medical assessment, it is therefore helpful to describe symptoms
over time:

| Observation | Question for your own notes |

| Nodule or abscess | Is the area deep and painful? |
| Drainage | Does the area open up or weep repeatedly? |
| Scar or induration | Does a change remain after a flare? |
| Daily life | Does sitting, walking, lifting the arm, sleep or clothing become harder? |

This makes it visible whether you are dealing with a single skin inflammation or a
recurrent pattern that should be discussed specifically.

Where symptoms call for particular attention

Typical regions are the armpits, groin, genital and perineal area, buttocks and skin folds under the breasts. Other sites are possible. However, location alone does not determine the diagnosis.

What you should describe when reporting symptoms

A good description includes:

- where the lesions appear,
- how often they recur,
- whether they are painful, open up or weep,
- whether scars or tracts remain,
- how much daily life and sleep are affected.

This helps turn individual complaints into a clinically relevant pattern.

What is often underestimated

Drainage, concerns about odour, questions about dressings, embarrassment and pain are not
side issues. They can determine whether someone is able to work, sleep, move
or even show intimate complaints at all. So don't just say
how big a spot is, but also what it changes in daily life.

What symptoms do not automatically mean

Not every nodule in the groin and not every wound on the buttocks is HS. Depending on the site and course, other causes can come into play. That is no reason to play down complaints. It is the reason to have them assessed professionally.

When you should take action

Recurrent painful lesions in typical regions belong in a dermatological consultation. In case of fever, rapid worsening, strongly increasing redness or very severe pain, prompt medical help is needed.

FAQ

Which symptom proves hidradenitis suppurativa?

No single symptom proves HS. The medical assessment combines typical lesions, typical body sites and a recurrent or chronic course.

Is pain part of hidradenitis suppurativa symptoms?

Yes. Pain can be very distressing with inflammatory nodules, abscesses, open lesions or scarred areas and should be described specifically during the appointment.

Are sinus tracts always visible early on?

No. Sinus tracts and scars can develop over time and may not yet be clearly visible when symptoms first appear.
