Hidradenitis Suppurativa: Symptoms, Diagnosis and Treatment

Overview

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition affecting areas with hair follicles and sweat glands — typically the armpits, groin, buttocks, and under the breasts. It causes painful nodules, abscesses, and, in advanced cases, tunnels (sinus tracts) under the skin that drain fluid and scar.

HS affects roughly 1% of the population and is more common in women, particularly after puberty. It's often confused with recurrent boils or poor hygiene, but HS is neither infectious nor hygiene-related — it's driven by follicular blockage and an overactive inflammatory immune response.

HS has a huge, underappreciated impact on quality of life due to pain, drainage, odor, and visible scarring, often causing significant psychological distress. It's frequently associated with obesity, metabolic syndrome, and other inflammatory conditions like Crohn's disease. Early treatment can prevent progression to severe, scarring disease.

Symptoms

Painful, deep nodules or lumps in armpits, groin, buttocks, or under breasts
Recurring abscesses that drain pus
Tunnels (sinus tracts) forming under the skin in advanced disease
Scarring and skin thickening over time
Blackheads in affected areas (a distinguishing feature)
Odor from drainage
Restricted movement due to scarring in severe cases
Flares often linked to hormonal cycles, stress, heat, or friction

Diagnosis

HS is diagnosed clinically based on:

Characteristic lesions in typical locations (armpits, groin, under breasts, buttocks)
Recurrence — at least 2 flares in 6 months
Staging (Hurley stages) — Stage 1 (isolated abscesses, no tunnels), Stage 2 (recurrent abscesses with limited tunneling), Stage 3 (widespread involvement with interconnected tunnels and scarring)
Ruling out other conditions — boils, cysts, and infections that can mimic HS

No blood test or biopsy is required for typical cases, though biopsy may be done to rule out other conditions. A dermatologist makes the diagnosis, ideally early, since delayed diagnosis is common and worsens outcomes.

Treatments

Topical and oral antibiotics — used for their anti-inflammatory (not just antimicrobial) effect; clindamycin, doxycycline
Biologics — adalimumab (Humira) is FDA-approved for HS and can be highly effective; other biologics (infliximab, secukinumab) are used off-label or newly approved
Hormonal therapy — spironolactone or oral contraceptives, since flares often correlate with hormonal cycles
Intralesional steroid injections — for individual painful nodules
Surgery — deroofing or wide excision of affected tissue for Hurley Stage 2-3 disease; can be curative for localized severe disease
Lifestyle — weight management (even modest weight loss can reduce flares), smoking cessation (strongly linked to HS severity), loose clothing, and gentle skin care avoiding friction
Pain management — chronic pain is common and often undertreated; ask specifically for a pain management plan

Your Care Plan

A step-by-step guide to navigating your condition, from finding the right doctors to advocating for the care you deserve.

Step 1: Doctors to See

Start with: A dermatologist, ideally one experienced with HS specifically (not all are). Early treatment prevents progression to severe scarring disease.

Build your team:

Surgeon (general or plastic) — for excision of severe, scarred tissue
Endocrinologist — if hormonal or metabolic factors (PCOS, insulin resistance) are involved
Pain management specialist — chronic pain from HS is often undertreated
Mental health professional — the psychological burden of HS is significant and deserves support
Registered dietitian — for weight management support if relevant

Step 2: Advocate for Yourself

HS is often misdiagnosed for years as recurrent boils or blamed on poor hygiene — it is neither. If you're told to just "keep the area clean" without any other treatment plan, seek a dermatologist experienced with HS. Ask about your Hurley stage — this determines whether biologics or surgery should be considered. Don't accept dismissiveness about pain; HS pain is significant and deserves proper management. If you're a candidate for adalimumab or another biologic and insurance denies it, your dermatologist's office can help appeal.

Step 3: Your Action Plan

See a dermatologist for formal diagnosis and Hurley staging.
Start anti-inflammatory treatment early — antibiotics or hormonal therapy for milder stages.
If disease is Hurley Stage 2 or higher, discuss biologic therapy (adalimumab) with your dermatologist.
Address lifestyle factors — smoking cessation and gradual weight management if applicable.
For persistent localized nodules, discuss intralesional steroid injections or surgical deroofing.
Build a pain management plan — don't accept unmanaged chronic pain.
Seek psychological support if HS is affecting your mental health — this is common and valid.
