Painful Boils? Why Hidradenitis Suppurativa Flares: Medical Next Steps

If you keep getting painful boils in areas like your armpits, groin, buttocks, or under the breasts, you may be dealing with hidradenitis suppurativa (HS). This is not just a simple skin infection or "bad acne." Hidradenitis suppurativa is a chronic inflammatory skin condition that can worsen over time without proper treatment.

Understanding why hidradenitis suppurativa flares happen — and what to do next — can help you regain control and reduce pain, scarring, and complications.

What Is Hidradenitis Suppurativa?

Hidradenitis suppurativa is a long-term inflammatory disease that affects hair follicles in areas where skin rubs together. It causes:

• Painful lumps under the skin
• Recurrent boils
• Abscesses that may drain pus
• Tunnels under the skin (called sinus tracts)
• Scarring

HS is not caused by poor hygiene, and it is not contagious. It is a medical condition linked to inflammation, immune system activity, hormones, and genetics.

Why Does Hidradenitis Suppurativa Flare?

Flares happen when inflammation increases in the hair follicles. While the exact cause of hidradenitis suppurativa is not fully understood, research shows that blocked hair follicles trigger an immune response, leading to painful nodules and abscesses.

Several factors can increase flare frequency or severity:

1. Friction and Sweat

Areas where skin rubs together are more vulnerable. Tight clothing, shaving, and heavy sweating can irritate follicles and trigger inflammation.

2. Hormonal Changes

Many people with hidradenitis suppurativa notice worsening symptoms:

• Before their menstrual cycle
• After pregnancy
• During times of hormonal shifts

Androgens (hormones present in both men and women) may play a role.

3. Smoking

Smoking is strongly linked to HS severity. It appears to increase inflammation and follicle blockage. People who smoke often experience more frequent and severe flares.

4. Obesity and Metabolic Factors

Excess weight increases skin friction and inflammatory signaling in the body. Weight management can significantly improve symptoms in some individuals.

5. Genetics

About one-third of people with hidradenitis suppurativa have a family history of the condition.

6. Stress

Stress does not cause HS, but it can worsen immune responses and increase flare frequency.

What a Hidradenitis Suppurativa Flare Feels Like

A flare may begin as:

• A tender bump under the skin
• Burning or itching before a lump forms
• Swelling that becomes increasingly painful
• Drainage of foul-smelling fluid
• Skin thickening or scarring over time

Early recognition matters. Treating flares promptly can reduce long-term damage.

Why You Shouldn't Ignore Recurrent Boils

Many people delay seeking care because they assume the boils are infections that will pass. But untreated hidradenitis suppurativa can lead to:

• Permanent scarring
• Skin tunnels (sinus tracts)
• Restricted movement from scar tissue
• Chronic pain
• Secondary infections
• Emotional distress and depression

In rare but serious cases, long-standing HS can increase the risk of certain skin cancers in affected areas.

If your boils keep returning in the same areas, taking a free assessment can help you understand if Hidradenitis Suppurativa may be causing your symptoms and guide your next steps toward getting proper care.

Medical Next Steps for Hidradenitis Suppurativa

If you suspect hidradenitis suppurativa, here's what to do next.

1. See a Healthcare Professional

A primary care doctor or dermatologist can diagnose HS based on:

• Location of lesions
• Recurrence pattern
• Physical examination

There is no single lab test for hidradenitis suppurativa. Diagnosis is clinical.

If you experience:

• Fever
• Rapidly spreading redness
• Severe swelling
• Signs of systemic infection

Seek urgent medical care immediately.

2. Understand Your Disease Stage

Doctors often classify hidradenitis suppurativa into three stages (Hurley stages):

• Stage I: Isolated abscesses without scarring or tunnels
• Stage II: Recurrent abscesses with some scarring and sinus tracts
• Stage III: Extensive interconnected tunnels and widespread scarring

Treatment depends on severity.

3. Treatment Options for Hidradenitis Suppurativa

There is no cure, but many effective treatments can reduce flares and prevent progression.

Topical Treatments (Mild Disease)

• Topical clindamycin (antibiotic)
• Antibacterial washes (such as chlorhexidine or benzoyl peroxide)

Oral Medications

• Oral antibiotics (for inflammation control, not just infection)
• Hormonal therapy (such as certain birth control pills or spironolactone)
• Metformin in some patients
• Oral retinoids in selected cases

Biologic Medications

For moderate to severe hidradenitis suppurativa, biologics that target specific parts of the immune system may be recommended. These medications can significantly reduce inflammation and flare frequency.

Steroid Injections

Injected directly into painful nodules to reduce swelling quickly.

Surgical Options

• Drainage of painful abscesses (short-term relief)
• Deroofing procedures (removal of tunnels)
• Wide excision surgery (for severe cases)

Surgery can be very effective for advanced hidradenitis suppurativa when medical therapy alone is not enough.

Lifestyle Changes That Can Reduce Flares

Medical treatment works best when combined with lifestyle support.

Consider:

• Wearing loose, breathable clothing
• Avoiding shaving over active lesions
• Using gentle cleansers
• Stopping smoking
• Managing weight if overweight
• Stress-reduction strategies

Weight loss and smoking cessation can significantly reduce flare frequency in many patients. While these changes are not cures, they can improve outcomes.

---

Pain Management During a Flare

Pain from hidradenitis suppurativa can be intense. Strategies include:

• Warm compresses
• Over-the-counter anti-inflammatory medications (if approved by your doctor)
• Prescription pain management for severe cases
• Early medical intervention before abscesses enlarge

Never attempt to squeeze or lance boils at home. This can worsen inflammation and cause deeper infection.

---

Mental Health Matters

Living with hidradenitis suppurativa can be physically and emotionally exhausting. Chronic pain, drainage, and scarring can affect:

• Self-esteem
• Relationships
• Work performance
• Mood

Depression and anxiety are more common in people with HS. If you feel overwhelmed, speak to a healthcare provider. Mental health support is an important part of treatment.

---

When to Seek Immediate Care

While hidradenitis suppurativa is usually chronic rather than life-threatening, seek urgent medical attention if you experience:

• High fever
• Severe spreading redness
• Rapidly worsening pain
• Signs of sepsis (confusion, rapid heart rate, low blood pressure)

These may signal a serious infection requiring emergency treatment.

---

Early Action Changes Outcomes

The earlier hidradenitis suppurativa is diagnosed and treated, the better the long-term outcome. Delays in diagnosis are common — sometimes 7 to 10 years — but early medical care can:

• Reduce scarring
• Prevent tunnel formation
• Decrease pain
• Improve quality of life

If you're experiencing recurring painful boils and want to better understand your symptoms before your doctor's appointment, a free AI-powered evaluation for Hidradenitis Suppurativa can help you identify key patterns and prepare important questions for your healthcare provider.

Final Thoughts

Hidradenitis suppurativa is a chronic inflammatory condition — not just recurring boils. Flares happen because of immune-driven inflammation in blocked hair follicles, often triggered by friction, hormones, smoking, weight, or genetics.

The condition can be painful and progressive, but it is treatable. Modern therapies, combined with lifestyle changes and early intervention, can dramatically improve symptoms and prevent complications.

If you suspect hidradenitis suppurativa or have recurring painful boils, speak to a doctor. Prompt medical care can prevent serious complications and improve your long-term health.
