Anal Skin Tags: What They Are, Whether They Are Piles, and How They Are Removed
The Lump That Is Usually Nothing — and Why People Worry Anyway
Anal skin tags are one of the commonest things a colorectal clinician sees and one of the least discussed things a patient ever asks about. They are small, soft flaps of skin at the edge of the anus, usually discovered by accident while washing, and almost everyone who finds one assumes the worst or assumes it is a pile. Most of the time it is neither. A skin tag is not a tumour, it is not infectious and it is not a haemorrhoid in the active sense of the word — it is stretched skin left behind after a swelling has settled. That said, the reason people search for this is reasonable: a lump in that part of the body is not something anyone can inspect properly on their own, and a small number of lumps that look like tags turn out to be something else. This article explains what tags are, how they differ from haemorrhoids, why the creams on the pharmacy shelf will not shrink them, what removal involves in the UK and what it costs, and which features mean a lump needs a clinician to look at it. We should also say at the start that our clinic does not remove skin tags — we treat internal haemorrhoids — so nothing here is a sales pitch for a procedure we offer.
What an Anal Skin Tag Actually Is
The skin around the anus is unusually loose and elastic, because it has to stretch every time you open your bowels. When the tissue underneath swells — a thrombosed pile, a flare of external haemorrhoids, the pressure of late pregnancy and delivery, or the inflammation around a healing tear — the overlying skin stretches to accommodate it. When the swelling goes down, the skin does not always shrink back. What is left is a redundant fold: skin-coloured or slightly darker, soft, usually painless, sometimes a few millimetres across and sometimes the size of a fingertip. Some people have one; some have several arranged around the opening. Clinicians sometimes call them perianal skin tags or, in examination notes, redundant anal tissue. The key point is that a tag contains no swollen blood vessel. It is skin, with a little connective tissue in its core, and that single fact explains almost everything else about how tags behave and how they are — and are not — treated.
Why They Form: The Usual Causes
The commonest route to a tag is a previous episode of swelling. A thrombosed external haemorrhoid — the sudden, painful purple lump caused by a clot under the skin — is the classic one: once the clot is reabsorbed over two or three weeks, a tag is frequently what remains. Repeated flares of external haemorrhoids stretch the skin a little further each time. Pregnancy and vaginal delivery are a very common cause, which is why so many women notice a tag for the first time in the months after a baby and assume it is a pile that has not gone away; our article on haemorrhoids after childbirth covers that period in detail. Chronic straining and hard stools contribute by the same mechanism of repeated stretching. Then there is the tag that marks a fissure: a small tear in the lining of the anal canal, usually at the back, which provokes swelling at its outer end and leaves a tag known as a sentinel pile. Less commonly, tags are associated with Crohn's disease, where they tend to be larger, firmer, more swollen or bluish, and may be accompanied by other perianal problems. And some people simply have them without any identifiable episode at all.
Skin Tag or Haemorrhoid? How to Tell Them Apart
This is the question behind most searches, and the honest answer is that the distinction is easier to make with a proctoscope than with a mirror — but there are useful clues. A skin tag is the same size every day. It does not swell when you strain, does not shrink when you lie down, does not bleed, and does not change colour. It is covered in ordinary skin and is usually painless unless it is rubbed raw. External haemorrhoids, by contrast, are swollen veins under the skin: they can look bluish, feel slightly spongy, get bigger with straining or after a long day, and ache. A thrombosed haemorrhoid is tense, tender and dark, and appears over hours. A prolapsed internal haemorrhoid looks different again — pink or red, moist, covered by the lining of the bowel rather than skin, and it comes down with a bowel movement and either goes back on its own or has to be pushed back; grade 3 and 4 internal haemorrhoids are routinely mistaken for external lumps by patients and sometimes by referrers. Bleeding is a strong signal: skin tags essentially never bleed on their own, so bright red blood on the paper points to something inside — usually an internal haemorrhoid or a fissure. Our guide to haemorrhoid types sets out the anatomy, and our article on a lump near the anus walks through the wider list of possibilities.
Can You Shrink a Haemorrhoid Skin Tag?
This is one of the most searched questions in the whole subject, and it deserves a direct answer: no cream, suppository, wipe or home remedy will shrink a skin tag. Haemorrhoid creams work — to the extent that they work — by soothing inflamed skin, reducing itch with a mild steroid, or numbing the area with a local anaesthetic. They act on swelling and inflammation. A tag is neither swollen nor inflamed; it is surplus skin, and there is nothing in it for a cream to shrink. What creams can legitimately do is calm a tag that has become irritated from rubbing or over-wiping, and settle any active haemorrhoid sitting next to it — which is why some people feel a cream has helped. If a lump genuinely shrinks over a week or two of treatment, it was almost certainly a swollen haemorrhoid or a resolving clot, not a tag. The same applies to the internet's other suggestions: tea tree oil, apple cider vinegar and similar applications do not remove tags and can cause painful chemical irritation on very sensitive skin. Our guide to haemorrhoid creams explains what each product type can realistically achieve.
Do Skin Tags Go Away on Their Own?
Established tags generally do not disappear. A lump that looks like a tag in the first few weeks after a thrombosed pile, a birth or a flare is often still partly swollen, and it can shrink considerably as the swelling settles over two to three months — so it is worth waiting before drawing conclusions. After that, what remains tends to be permanent. It is also worth knowing that tags are not progressive: a tag does not grow into a haemorrhoid, does not turn into anything else, and does not need to be removed to prevent future problems. If a tag appears to be getting bigger over time, the usual explanation is repeated swelling episodes — new flares stretching the skin further — rather than the tag itself growing, and that points to managing the underlying cause. A lump that keeps growing steadily without any flares is a different matter and should be examined.
When a Skin Tag Needs Checking
The overwhelming majority of tags are harmless, but a lump in this area should be looked at by a clinician at least once, because a small number of other conditions can resemble one and early assessment is straightforward. See your GP rather than waiting if a lump is getting steadily larger, feels firm or hard rather than soft, is ulcerated, bleeds from its surface, has an irregular or warty cauliflower-like surface, or is accompanied by persistent itching, discharge, pain or a change in bowel habit. Warty lumps may be anal warts, which are caused by HPV and treated differently. A firm, growing or ulcerated lump at the anal margin can occasionally be an anal cancer, which is uncommon but is precisely the kind of thing that is mistaken for a tag; our article on haemorrhoids or bowel cancer covers the red-flag symptoms for both. Tags that are large, swollen or bluish in someone who also has abdominal pain, diarrhoea or weight loss can be a sign of Crohn's disease and warrant investigation. None of these is likely. The point is that a single examination settles the question, and a photograph or a website cannot.
Living With Skin Tags: Hygiene and Irritation
Most people with tags never need them removed. The practical problem, when there is one, is hygiene: stool can collect in the folds around a tag, making cleaning fiddly, and incomplete cleaning leads to itching and soreness, which in turn leads to vigorous wiping and more irritation. A few simple habits break that cycle. Clean with water rather than repeated dry paper — a shower head, a bidet, or damp unscented toilet paper — and pat dry rather than rub. Avoid perfumed wipes, bubble baths and strong soaps, which are a common and under-recognised cause of perianal irritation. Wear breathable cotton underwear. Keep stools soft and easy to pass, because straining and hard stools inflame the whole area; a high fibre diet with enough fluid does quiet work here. If itching is the dominant symptom, especially at night, our article on itchy bottom at night covers the wider causes and what to do about them.
How Anal Skin Tags Are Removed
When a tag causes genuine hygiene problems, repeated irritation, or significant distress, removal is a minor procedure. It is usually done under local anaesthetic in a clinic or day-surgery setting: the area is numbed with an injection, and the tag is snipped off at its base with fine scissors or a scalpel, or removed with a cautery device or laser that seals small vessels as it cuts. Small tags often need no stitches; larger ones may have one or two dissolvable sutures. Several tags can be removed at once, although many surgeons prefer to be conservative and stage the removal of multiple large tags, because taking away too much perianal skin in one go risks the anal opening narrowing as it heals — a complication called anal stenosis that is far more troublesome than the tags ever were. One situation deserves particular caution: a sentinel pile should not be removed on its own, because the fissure underneath it is the real problem, and cutting off the tag without treating the fissure leaves the pain in place. Similarly, surgeons are usually reluctant to remove tags in people with active perianal Crohn's disease, because wounds in that setting can heal poorly. What should not be done is removing a tag yourself. Tying it off with thread, cutting it or using over-the-counter skin tag removal products designed for the neck or armpit can cause bleeding, infection and considerable pain in an area that is impossible to keep clean — and removes the chance of anyone confirming what the lump actually was.
Recovery After Removal
Recovery is usually quick but not trivial, because the skin around the anus is among the most sensitive in the body and it is used every day. Expect soreness for several days to two weeks, most noticeable during and just after bowel movements, and a little spotting of blood on the paper. Simple painkillers, warm shallow baths, a stool softener started before the procedure, and plenty of fluid all make the first bowel movements easier. Most people are back at desk work within a day or two, though sitting may be uncomfortable for a few days and strenuous exercise is best postponed until the wound has settled. The main complications are bleeding, infection, delayed healing and, rarely, narrowing if too much tissue was removed. Tags can also recur if the process that created them — repeated haemorrhoid flares, a fissure, chronic straining — carries on, which is why the underlying cause matters as much as the removal itself.
Cost and Availability in the UK
Anal skin tag removal is generally regarded by the NHS as a cosmetic procedure and is not routinely offered, although a tag causing significant symptoms, or one where the diagnosis is uncertain, may still be assessed and managed through your GP and a hospital referral. Privately, removal is offered by minor-surgery and dermatology clinics as well as by colorectal surgeons. As at September 2026, published prices at private skin-surgery clinics start at roughly £395 to £595 for a single tag, with the total rising with the number and size of tags treated; some clinics charge a separate consultation fee, and removal by a colorectal surgeon in a private hospital typically costs more. Before booking anywhere, ask whether the quote covers the consultation, all the tags you want treated, any histology if the tissue is sent to the laboratory, and a follow-up review. Ask too who will perform the procedure and how often they remove perianal tags specifically, because the risk of over-excision is a question of experience, not equipment. Our broader breakdown of haemorrhoid treatment cost in the UK sets out how private quotes are structured and the extras they often leave out.
What We Do and Do Not Treat
Being clear about this saves wasted journeys. Our clinics in Glasgow and London provide eXroid electrotherapy for internal haemorrhoids: a low-dose direct current applied to the base of the haemorrhoid, above the dentate line, which seals off the feeding vessel so the cushion shrinks over the following weeks, with no cutting and no general anaesthetic. We do not remove skin tags, and we do not treat purely external haemorrhoids, fissures, warts or polyps. Treating internal haemorrhoids will not make an existing skin tag disappear, because a tag contains no feeding vessel to act on. Where eXroid is relevant to someone with tags is the situation that is surprisingly common: the lump outside is a tag, but the bleeding, the prolapse or the recurring flares that stretched the skin in the first place are coming from internal haemorrhoids that have never been properly assessed. Treating those can stop new tags forming, even though it does nothing for the ones already there. We are also candid that the treatment is uncomfortable — many patients describe it as properly painful while it is happening, although it is short and settles within minutes — and that some patients need more than one session. At an examination the clinician will tell you what each lump actually is, including any that are outside what we treat, and where to go for those.
Where to Start
If you have a soft, painless, skin-coloured flap that has not changed in months, the most likely explanation is a harmless skin tag, and you have two sensible options: leave it alone and manage hygiene, or have it removed if it genuinely bothers you. In either case, having it examined once is worth doing — your GP can do this, and it is the only way to be certain. If the lump is changing, firm, bleeding or warty, see your GP promptly rather than waiting. If you also have bleeding on the paper, something that comes down when you open your bowels, or itching and discomfort that keep coming back, the tag may be the visible sign of internal haemorrhoids that are worth treating in their own right. Our severity test takes a couple of minutes and gives an indication of what you may be dealing with, though it is not a diagnosis. You can read about our procedure in full, book an appointment at our Glasgow or London clinic, or contact us with a question. A consultation with examination is £365, consultation and treatment on the same visit is £1,095, and a follow-up treatment if needed is £795. If what you have turns out to be something we do not treat, we will tell you so at the consultation.
