A lump near the anus is one of the more common reasons for visiting a proctologist. It may appear suddenly or develop gradually; it may be very painful or almost painless. This is exactly why it causes concern — patients often do not know whether it is a haemorrhoid, a clot, an abscess, a skin tag or something more serious.
In most cases, the cause of a lump around the anus is benign, but you should not diagnose it yourself. This article explains the most common causes of a lump near the anus, when the symptom requires urgent assessment and what a proctology consultation in Gdańsk looks like.

Why should you not diagnose a lump near the anus on your own?
Patients often search online for phrases such as “hard ball near the anus”, “lump near the anus hurts”, “bluish lump near the anus”, “is it a haemorrhoid or cancer” or “painful growth near the anus”. This is understandable — the anal area is intimate, and the symptoms often cause embarrassment, anxiety and a tendency to postpone the visit.
The problem is that different proctological conditions may look similar. A lump near the anus may be related to haemorrhoids, perianal thrombosis, a skin tag, abscess, fistula, anal fissure, dermatological lesion, viral wart, inflammation or, less commonly, a lesion requiring more urgent diagnostics.
That is why examination is essential. Only after inspecting the anal area and taking a medical history can the doctor say whether the lesion is benign, whether it requires treatment, a procedure, observation or further diagnostics.
“Patients often come convinced that they have haemorrhoids. After examination, it turns out that the lump is caused by perianal thrombosis, an abscess, a skin tag or a completely different lesion. Symptoms may be similar, but treatment can be entirely different.”
— Dr Kamil Smok, surgeon and proctologist
The most common causes of a lump near the anus
A lump around the anus may have many causes. Below we discuss the most common ones, but this list does not replace a medical examination.
1. Haemorrhoids
Haemorrhoids are enlarged haemorrhoidal cushions. They may cause rectal bleeding, itching, burning, a feeling of incomplete evacuation, discomfort or tissue prolapse during straining. Not every haemorrhoid is painful. Internal haemorrhoids often cause bleeding rather than pain.
If the main problem is chronic haemorrhoid symptoms, such as bleeding, itching, prolapse or recurrent discomfort, more information is available on the page: haemorrhoid treatment in Gdańsk. This article, however, focuses more broadly on a lump near the anus and the possible causes of this symptom.
2. Perianal thrombosis — a sudden painful lump
Perianal thrombosis, also called thrombosed external haemorrhoid or perianal blood clot, usually appears suddenly. Patients often describe it as a hard, bluish or purple lump near the anus that is very painful and makes sitting difficult.
It is one of the most common causes of acute pain around the anus. With fresh symptoms and very severe pain, early consultation matters, because the doctor may consider conservative or procedural treatment depending on the duration of symptoms and the appearance of the lesion.
You can read more about this specific condition here: perianal thrombosis — symptoms and treatment.
3. Skin tag near the anus
A skin tag is excess skin around the anus. It may remain after perianal thrombosis, inflammation, childbirth, chronic haemorrhoids or prolonged skin irritation. It usually does not cause severe pain, but it may interfere with hygiene, cause moisture, itching, irritation or aesthetic discomfort.
Not every skin tag requires removal. The decision depends on symptoms, the size of the lesion, hygiene difficulties and the patient’s expectations.
4. Perianal abscess
A perianal abscess is an inflammatory condition with pus accumulation around the anus. It may cause a painful lump, increasing swelling, redness, throbbing pain, fever and feeling unwell. This is not a condition to wait out.
An abscess usually requires urgent medical assessment, because treatment often involves incision and drainage. Ointments, sitz baths or antibiotics without surgical assessment may be insufficient.
5. Anal fissure with swelling or a sentinel tag
An anal fissure is a painful tear in the lining of the anal canal. It typically causes severe pain during bowel movements, burning after passing stool and sometimes bright red blood. In a chronic fissure, a skin tag or sentinel tag may appear at the edge of the anus.
The patient may then think the problem is haemorrhoids, while the main cause of pain is a fissure. More information is available here: anal fissure — treatment with botulinum toxin.
6. Skin lesions, warts, condylomas and dermatological conditions
Not every lump around the anus has a strictly proctological cause. Sometimes it is a skin lesion: fibroma, wart, condyloma, inflammation, cyst, irritation, skin disease or a lesion after trauma or infection.
Such lesions require assessment, especially if they grow, bleed, are uneven, change colour, ulcerate, hurt or recur.
7. Less commonly — lesions requiring more urgent diagnostics
Cancerous lesions of the anal and rectal area are less common than haemorrhoids, thrombosis or skin tags, but they must not be ignored. Particular attention should be paid to lumps that grow, are hard, uneven, ulcerated, bleed, do not heal, cause increasing pain or are accompanied by general symptoms.
This does not mean that every lump is a serious disease. It means that without examination, it cannot be assessed responsibly.
Lump near the anus — what can it mean?
| Symptom | Possible cause | What should you do? |
|---|---|---|
| sudden, very painful, hard lump | perianal thrombosis | early consultation, especially in the first days |
| soft lump, itching, bleeding | haemorrhoids | proctological examination and assessment of disease stage |
| painless lump interfering with hygiene | skin tag | assessment whether treatment or removal is needed |
| increasing pain, swelling, fever | perianal abscess | urgent medical consultation |
| pain during stool, burning, bright blood | anal fissure, sometimes a sentinel tag | diagnostics and fissure treatment |
| lesion grows, bleeds, ulcerates or does not heal | lesion requiring broader diagnostics | do not delay medical assessment |
Haemorrhoid or perianal thrombosis — how to tell the difference?
This is one of the most common questions patients ask. The answer is not always possible without examination, but some features may suggest what is happening.
| Feature | Haemorrhoids | Perianal thrombosis |
|---|---|---|
| Onset | often gradual, recurrent | sudden, often within a few hours |
| Pain | may be mild or absent | often very severe |
| Appearance | soft, prolapsing or enlarged lump | hard, tense, often bluish or purple lump |
| Bleeding | common, usually bright red | may occur, but pain dominates |
| Management | assessment of disease stage and treatment selection | early assessment, especially with fresh severe pain |
In practice: if the lump appeared suddenly, is hard, bluish and very painful, perianal thrombosis is often suspected. If the symptoms have been developing for longer, recur, and bleeding, itching or prolapse dominate, haemorrhoidal disease is more likely. However, the final diagnosis requires examination.
When does a lump near the anus require urgent consultation?
Not every lump requires an immediate procedure, but there are situations in which it is not worth waiting. Early medical assessment is especially important when symptoms are acute, worsening or accompanied by general symptoms.
See a doctor urgently if:
- the lump appeared suddenly and is very painful,
- pain makes sitting, walking or passing stool difficult,
- the lesion is bluish, purple, tense or growing quickly,
- fever, chills, weakness or feeling unwell occurs,
- swelling or redness is increasing,
- rectal bleeding occurs,
- the lesion is ulcerated, oozing, not healing or growing,
- it is accompanied by unintentional weight loss, anaemia, change in bowel habits or abdominal pain,
- you are not sure whether it is a haemorrhoid, thrombosis, abscess or another lesion.
If heavy bleeding, black stools, fainting, severe abdominal pain, high fever or rapid deterioration of general condition occurs, urgent medical help may be needed.
What should you do when a lump near the anus appears?
The most common mistake is postponing the visit and self-treating it “as haemorrhoids”. Ointments, suppositories or sitz baths may sometimes reduce symptoms, but they do not answer the most important question: what is the lump?
If a lump near the anus appears:
- do not pierce, squeeze or try to remove it yourself,
- do not use irritating preparations without medical advice,
- avoid strong straining and prolonged sitting on the toilet,
- keep stools soft and stay hydrated, if you have no contraindications,
- watch for fever, bleeding, increasing swelling or rapid deterioration,
- book a proctology consultation, especially if the pain is severe or the symptom appeared suddenly.
In many cases, early consultation helps relieve symptoms, reduce pain and avoid accidental treatment of the wrong condition.
“Not every lump near the anus requires a procedure, but every lump requires reasonable assessment. Sometimes conservative treatment is enough, sometimes early intervention is needed, and sometimes the most important thing is to rule out a cause other than haemorrhoids.”
— Sara Godyńska, MD, proctologist
What does a proctology consultation for a lump look like?
A proctology consultation begins with a conversation. The doctor asks when the lump appeared, whether it hurts, whether it bleeds, whether it is growing, whether there is fever, constipation, diarrhoea, itching, burning, hygiene difficulties or previous proctological problems.
The examination may include:
- inspection of the anal area,
- gentle palpation, if possible,
- digital rectal examination, if needed and not excessively painful,
- anoscopy, if the doctor wants to assess the anal canal and the final part of the rectum,
- discussion of the diagnosis and treatment plan.
If the pain is very severe, the doctor adjusts the scope of examination to the situation. The purpose of the visit is not to increase discomfort, but to determine the cause of the symptom and choose the safest management.
Can a lump near the anus disappear on its own?
Sometimes yes. A small skin tag, minor swelling or some inflammatory lesions may calm down. Perianal thrombosis may gradually absorb over several weeks. However, this does not mean that every lump should be waited out.
If the lump is painful, growing quickly, bleeding, has an unusual appearance, is accompanied by fever or keeps coming back, diagnostics are needed. Waiting may delay treatment of an abscess, thrombosis, fissure or another lesion requiring specific management.
Can a lump near the anus be cancer?
Most often, a lump near the anus is not cancer. Much more common causes include haemorrhoids, perianal thrombosis, skin tag, inflammation or anal fissure. However, this does not mean the symptom can be ignored.
Particularly concerning are lesions that:
- grow or change shape,
- are hard, uneven, ulcerated or not healing,
- bleed without a clear cause,
- cause chronic pain, discharge or itching,
- occur together with weight loss, anaemia, change in bowel habits or abdominal pain.
In such situations, it should not be assumed that it is “just a haemorrhoid”. Medical assessment and sometimes further diagnostics are needed.

Frequently asked questions
Is a lump near the anus always a haemorrhoid?
No. A lump near the anus may be a haemorrhoid, but it may also be perianal thrombosis, a skin tag, an abscess, an anal fissure, a skin lesion or another condition. That is why a proctological examination is worth doing.
What does a hard ball near the anus mean?
A hard ball near the anus may suggest perianal thrombosis, especially if it appeared suddenly and is painful. However, it may also have other causes, so it requires medical assessment.
Does a painful lump near the anus have to be removed?
Not always. The decision depends on the cause of the lump, duration of symptoms, severity of pain and examination. In perianal thrombosis, a short procedure may be considered in some patients, while conservative treatment is enough in others.
Can a lump near the anus disappear on its own?
Sometimes yes, but it is not worth relying only on observation if the lump hurts, grows, bleeds, appeared suddenly or is accompanied by fever. In such situations, consultation is needed.
Can a lump near the anus be cancer?
Most often the cause is benign, but this cannot be assessed without examination. Growing, ulcerated, non-healing, bleeding lesions or lesions associated with general symptoms require medical diagnostics.
When should I urgently see a doctor for a lump near the anus?
Urgent consultation is recommended if the lump appeared suddenly, is very painful, grows quickly, is accompanied by fever, increasing swelling, redness, bleeding or feeling unwell.
Which proctologist should I see in Gdańsk?
At Wyspa Medycyny Przyjaznej, consultations are provided by Sara Godyńska, MD, Justyna Szul, MD and Dr Kamil Smok. You can start with a proctology consultation in Gdańsk.
Do you have a lump, pain, bleeding or swelling near the anus?

Book a proctology consultation →Summary
A lump near the anus is a symptom that should not be ignored. Most often the cause is benign, but without examination it is impossible to responsibly determine whether it is a haemorrhoid, perianal thrombosis, skin tag, abscess, fissure, dermatological lesion or another problem.
Early consultation is especially important if the lump appeared suddenly, is very painful, bluish, growing quickly, bleeding, accompanied by fever or feeling unwell. Early diagnostics help start the right treatment faster and avoid accidental use of “haemorrhoid” preparations when the cause is different.
If you notice a lump near the anus, pain, bleeding, itching, burning or swelling, book a proctology consultation in Gdańsk.
