Hidradenitis Suppurativa (HS) is a chronic, inflammatory skin condition that causes painful, recurring lumps, abscesses, and tunnels in areas where skin rubs together—such as the armpits, groin, thighs, buttocks, and under the breasts. Despite affecting millions of people worldwide, HS is often misdiagnosed in its early stages as acne, boils, or simple skin infections. This misunderstanding can lead to delayed treatment, allowing the condition to worsen over time. Recognizing the early signs and symptoms of HS is crucial for getting a proper diagnosis and starting treatment as soon as possible.
The first signs of HS typically appear after puberty and may begin as small, tender lumps under the skin. These lumps can flare up repeatedly in the same areas and gradually become larger, more painful, and interconnected. While the severity of HS varies from person to person, early symptoms may include:
✔️ Recurring Painful Lumps – Small, pea-sized lumps that develop deep under the skin and may be red, swollen, and tender to the touch.
✔️ Blackheads in Clusters – Tiny blackheads that form in double or multiple comedones, often found in affected areas.
✔️ Abscesses That Drain Fluid – Swollen lumps that burst and release pus, sometimes leaving open wounds that take time to heal.
✔️ Burning or Itching Sensations – Before lumps appear, some people experience itching, burning, or discomfort in the affected areas.
In the early stages, symptoms may come and go, making it easy to dismiss them as minor skin issues. However, without proper treatment, HS can progress to larger, painful abscesses, leading to scarring, restricted movement, and deep tunnels (sinus tracts) under the skin.
Because HS is a progressive condition, early intervention is key to managing symptoms, reducing flare-ups, and preventing complications. In this article, we’ll discuss the first warning signs of HS, how to distinguish it from other skin conditions, and when to seek medical advice. If you or someone you know is experiencing recurring skin lumps or abscesses, understanding these early symptoms can make all the difference in getting the right diagnosis and treatment.
First Warning Signs of HS
Hidradenitis Suppurativa (HS) often begins subtly, with early warning signs that can be mistaken for minor skin issues like ingrown hairs, pimples, or simple boils. However, these symptoms tend to recur in the same areas and may gradually worsen over time. Recognizing the first warning signs is crucial for early diagnosis and treatment, which can help manage the condition before it progresses to more severe stages.
One of the most common early signs of HS is the development of small, tender lumps under the skin. These lumps often appear in warm, moist areas where skin rubs together, such as the armpits, groin, inner thighs, under the breasts, and buttocks. The lumps may start as firm, pea-sized nodules that are slightly painful or tender to the touch.
Over time, these lumps may:
✔️ Come and go repeatedly in the same location.
✔️ Increase in size and tenderness, especially before bursting.
✔️ Feel like deep, swollen nodules beneath the skin.
Another early sign of HS is the presence of blackheads in clusters. Unlike regular blackheads, which appear individually on the face or nose, HS-related blackheads tend to form double-headed comedones (black dots next to each other) in the affected areas.
Additionally, many people with HS report experiencing a burning, tingling, or itching sensation in the skin before a lump appears. This discomfort can be an early indicator of inflammation beneath the surface, even before a visible nodule develops.
In its initial stages, HS symptoms may seem mild and sporadic, leading many people to ignore or dismiss them. However, because HS is a progressive condition, these early lumps and skin changes can evolve into larger, painful abscesses, scarring, and sinus tract formation if left untreated.
Recognizing these first warning signs is the first step toward getting an accurate diagnosis and starting treatment early, which can help slow the progression of HS and improve long-term outcomes.
How to Distinguish HS from Other Skin Conditions
Hidradenitis Suppurativa (HS) is often misdiagnosed in its early stages because it shares similarities with several other common skin conditions, such as acne, boils, folliculitis, cysts, and even ingrown hairs. However, HS has distinct characteristics that set it apart from these conditions. Recognizing these differences is crucial for early diagnosis and treatment, as mistaking HS for a minor skin issue can lead to delayed medical care and worsening symptoms. Below, we’ll break down how HS differs from other skin conditions and what key signs to look for.
1. HS vs. Acne
Many people initially confuse HS with acne, as both conditions can cause blackheads, pimples, and cyst-like lumps. However, HS and acne have significant differences in how they develop and behave over time.
✔️ HS primarily occurs in skin folds (armpits, groin, buttocks, under the breasts), while acne typically affects the face, chest, and back.
✔️ HS lesions are deep, painful nodules, whereas acne consists of surface-level whiteheads, blackheads, and pustules.
✔️ HS tends to form sinus tracts (tunnels) under the skin, which do not occur with acne.
✔️ Acne is linked to clogged pores and bacteria, while HS is believed to be related to inflammation and immune system dysfunction.
2. HS vs. Boils (Furuncles and Carbuncles)
Because HS often begins as tender, swollen lumps, it is frequently mistaken for boils, which are painful bacterial infections of hair follicles. While both conditions can cause pus-filled abscesses, there are clear distinctions:
✔️ Boils usually appear as isolated lumps, while HS causes recurring flare-ups in the same areas.
✔️ Boils heal completely after draining, whereas HS lesions may persist, return, or worsen over time.
✔️ HS often leads to scarring and sinus tract formation, while boils do not typically cause long-term skin damage.
✔️ Boils are caused by bacterial infections, whereas HS is an inflammatory condition with no clear bacterial trigger.
3. HS vs. Folliculitis
Folliculitis is a common skin condition that occurs when hair follicles become inflamed or infected, leading to red bumps, pus-filled pimples, and irritation. While HS and folliculitis can both affect hair-bearing areas, there are key differences:
✔️ Folliculitis consists of small, surface-level bumps that resemble razor burn or tiny pimples.
✔️ HS lesions are deeper, larger, and more painful compared to folliculitis.
✔️ Folliculitis can clear up quickly with antibacterial treatment, while HS tends to persist and worsen over time.
✔️ HS is associated with sinus tract formation, whereas folliculitis does not cause tunnels or extensive scarring.
4. HS vs. Cysts (Epidermoid or Sebaceous Cysts)
Cysts are fluid-filled lumps that develop under the skin due to blocked oil glands. While both cysts and HS can cause firm, swollen nodules, there are notable distinctions:
✔️ Cysts usually have a visible central opening or pore, which HS nodules do not.
✔️ Cysts tend to remain in one spot, while HS lesions spread and reoccur in the same regions.
✔️ Cysts grow slowly and are usually not painful, whereas HS nodules flare up suddenly, become inflamed, and cause significant pain.
✔️ HS causes sinus tracts and long-term scarring, while cysts do not lead to widespread tissue damage.
5. HS vs. Ingrown Hairs
Ingrown hairs can cause red, irritated bumps that sometimes fill with pus and resemble early HS nodules. However, they differ in several ways:
✔️ Ingrown hairs are caused by trapped hair follicles, whereas HS results from inflammation, not blocked hairs.
✔️ Ingrown hairs typically resolve on their own or with exfoliation, while HS lesions persist and worsen over time.
✔️ HS lesions often lack a visible hair trapped beneath the skin, which is common in ingrown hairs.
✔️ HS affects deeper layers of skin and leads to abscesses and scarring, unlike simple ingrown hairs.
Key Takeaways: How to Recognize HS
If you’re experiencing recurring, painful skin lumps, it’s important to assess whether your symptoms align with HS or another condition. Here are red flags that suggest HS rather than a common skin issue:
✔️ Chronic Recurrence – If you experience painful lumps that appear in the same areas repeatedly, it’s more likely to be HS than a random boil or cyst.
✔️ Location of Lesions – HS primarily affects areas where skin rubs together, such as the armpits, groin, thighs, buttocks, and under the breasts.
✔️ Deep, Painful Nodules – Unlike acne or folliculitis, HS nodules develop deep under the skin, causing significant pain and tenderness.
✔️ Sinus Tracts and Scarring – If you notice tunnels forming under the skin or permanent scars, it’s a strong indicator of HS.
✔️ Abscesses That Drain but Return – If a lump bursts and releases pus, only to reappear later in the same spot, it is likely not a simple boil or cyst.
Hidradenitis Suppurativa is frequently misdiagnosed because its symptoms overlap with many common skin conditions. However, by paying attention to recurrence, severity, and affected areas, you can differentiate HS from other conditions and seek the appropriate medical care. Early diagnosis is crucial for preventing disease progression and finding the right treatment plan.
If you suspect you may have HS rather than acne, boils, or folliculitis, it’s important to track your symptoms and seek medical advice as soon as possible. The sooner you receive an accurate diagnosis, the better your chances of managing HS effectively and improving your quality of life.
When and How to Seek Medical Advice for HS
Recognizing the signs of Hidradenitis Suppurativa (HS) is the first step, but knowing when and how to seek medical advice is just as important. Because HS can be progressive, meaning it worsens over time, early diagnosis and treatment can help slow its progression, reduce flare-ups, and improve quality of life. Many people delay seeking medical help due to misdiagnosis, embarrassment, or the assumption that it’s just a temporary skin issue. However, consulting a healthcare provider as soon as symptoms appear can make a significant difference in managing the condition effectively.
When to Seek Medical Advice for HS
While some people may experience mild flare-ups that resolve on their own, there are several signs that indicate it’s time to see a doctor. If you experience any of the following, scheduling a medical consultation should be a priority:
✔️ Recurring Skin Lumps or Abscesses – If you develop painful, swollen lumps in the same areas repeatedly, it’s a strong sign that your symptoms may not be simple acne, boils, or ingrown hairs. HS tends to flare up in the same areas over time, leading to more severe skin damage if left untreated.
✔️ Persistent or Worsening Pain – Mild discomfort may be manageable at first, but as HS progresses, the pain can become intense and debilitating. If your symptoms are affecting your daily activities, mobility, or ability to sleep, it’s time to seek help.
✔️ Drainage of Pus or Unpleasant Odor – HS abscesses often burst and release pus, which may have a strong, unpleasant smell. If this happens frequently, it can indicate infection or chronic inflammation, requiring medical intervention.
✔️ Formation of Sinus Tracts (Tunnels) – If you notice interconnected lumps or tunnels forming under the skin, this is a sign of advanced HS (Hurley Stage 2 or 3). These tracts do not heal on their own, and medical treatment is necessary to prevent complications.
✔️ Scarring and Skin Thickening – If previous flare-ups have led to visible scars, skin thickening, or restricted movement, medical advice is essential. Scarring in HS can be permanent, and early treatment can help prevent further damage.
✔️ Emotional and Mental Health Impact – Living with HS can take a toll on mental well-being, leading to anxiety, depression, and social withdrawal. If HS is affecting your self-esteem or emotional health, discussing treatment options with a doctor can help improve both physical and mental well-being.
✔️ Difficulty Managing Symptoms with Over-the-Counter Treatments – If antibiotic creams, warm compresses, or home remedies aren’t working, it’s time to consult a doctor. HS typically requires prescription medications, medical procedures, or lifestyle modifications to manage symptoms effectively.
How to Seek Medical Advice for HS
If you recognize the symptoms of HS and need medical advice, knowing where to start can make the process easier. Below are the key steps to seeking medical care for HS.
1. Schedule an Appointment with a Healthcare Provider
Your first step should be to schedule an appointment with a primary care physician (PCP) or dermatologist. While a PCP can evaluate symptoms and prescribe initial treatments, a dermatologist specializes in skin conditions and may offer more targeted treatment options.
✔️ Find a doctor experienced in HS. Not all physicians are familiar with HS, so researching dermatologists or wound care specialists with HS expertise can ensure proper diagnosis and treatment.
✔️ Prepare for the appointment by tracking your symptoms, including when flare-ups occur, how long they last, and what treatments you’ve tried.
✔️ Mention any family history of HS, as genetics may play a role in developing the condition.
2. Be Ready to Describe Symptoms in Detail
During your appointment, your doctor will ask about:
✔️ Where you experience flare-ups (common areas include the armpits, groin, thighs, and under the breasts).
✔️ The frequency and severity of symptoms – Do lumps appear every few weeks? Have they worsened over time?
✔️ Pain levels and any mobility issues caused by HS.
✔️ Previous treatments attempted (antibiotics, over-the-counter creams, warm compresses, etc.).
✔️ How HS is affecting your daily life, including work, exercise, and emotional well-being.
Providing detailed and honest responses will help your doctor determine the best treatment plan.
3. Request a Proper Diagnosis
Because HS is often misdiagnosed as acne, boils, or folliculitis, it’s important to ensure your doctor correctly identifies the condition. If your symptoms match Hurley Stage 1 HS, your doctor may start with antibiotics or lifestyle recommendations. For more advanced cases (Stage 2 or 3), they may refer you to a dermatologist or surgeon for more intensive treatments.
4. Discuss Treatment Options
Once diagnosed, your doctor will outline a personalized treatment plan, which may include:
✔️ Topical or oral antibiotics to reduce inflammation.
✔️ Steroid injections to shrink painful lumps.
✔️ Biologic medications (such as Adalimumab) for severe HS.
✔️ Surgical options for drainage or removal of chronic lesions.
✔️ Lifestyle changes such as weight management, quitting smoking, and skincare modifications.
Discuss all available options and ask about potential side effects, long-term effectiveness, and insurance coverage before starting any treatment.
5. Follow Up Regularly
HS is a chronic condition, meaning long-term management is necessary. Regular check-ups with your doctor will help monitor symptoms and adjust treatments as needed. If your current treatment plan isn’t working, don’t hesitate to advocate for adjustments or second opinions.
Seeking medical care for HS early can make a huge difference in symptom control, pain management, and overall quality of life. If you notice recurring, painful lumps or other symptoms, don’t wait—schedule an appointment with a doctor as soon as possible. Early intervention can prevent complications, reduce flare-ups, and help you manage HS more effectively in the long run.
Conclusion: Taking Control of Your HS Journey
Hidradenitis Suppurativa (HS) is a chronic, painful, and often misunderstood condition that can significantly impact daily life. Because its early symptoms—small, recurring lumps, abscesses, and skin irritation—are often mistaken for acne, boils, or folliculitis, many people go undiagnosed for years. Recognizing the first warning signs of HS and understanding how it differs from other skin conditions is crucial for seeking timely medical care and preventing disease progression.
If you experience painful, recurring skin lesions in areas where skin rubs together—such as the armpits, groin, buttocks, or under the breasts—it’s important to consider the possibility of HS. Unlike common skin infections or acne, HS is a progressive condition that can lead to scarring, sinus tract formation, and long-term discomfort if left untreated. Seeking medical advice early can help manage symptoms, slow down its progression, and improve overall quality of life.
When and how you seek medical care matters. If your symptoms are persistent, painful, or worsening, scheduling an appointment with a primary care physician or dermatologist is the first step. Because not all doctors are familiar with HS, being prepared to describe your symptoms, flare-up frequency, and past treatments can help ensure a proper diagnosis. Working closely with a knowledgeable healthcare provider allows you to explore treatment options, including medications, lifestyle changes, and surgical interventions if needed.
Most importantly, you are not alone in this journey. While living with HS can be challenging, connecting with support groups, advocacy organizations, and medical professionals can provide valuable resources and emotional support. By taking a proactive approach to your health, treatment, and self-care, you can better manage HS and regain control over your life. Seeking medical care is the first step toward relief, understanding, and long-term well-being.
