TL;DR:
If you’ve noticed sudden, intense pain near your anus, coupled with swelling or a firm lump, you may be dealing with a thrombosed hemorrhoid. While most hemorrhoids are uncomfortable, a thrombosed hemorrhoid takes it to another level, causing sharp pain due to a blood clot forming inside the swollen vein.
So, how to tell if a hemorrhoid is thrombosed? It often comes down to a few key symptoms: severe tenderness, a visible or palpable lump near the anal opening, bluish or purplish skin discoloration, and pain that may worsen when sitting or passing stool.
This guide will walk you through how to recognize a thrombosed hemorrhoid, why it happens, and what steps you can take to relieve the pain and promote healing.
A thrombosed hemorrhoid is a type of external hemorrhoid that becomes especially painful when a blood clot (or thrombus) forms inside it. This happens when blood flow is restricted in the swollen vein, causing the blood to pool and harden into a clot. The result? A tender, often bluish or purplish lump near the anal opening that causes sudden, sharp discomfort.
So, how to tell if a hemorrhoid is thrombosed? Unlike typical hemorrhoids that may itch or cause mild irritation, a thrombosed hemorrhoid typically presents with:
These symptoms occur because the trapped blood stretches the sensitive skin around the anus, creating intense pressure. While the clot itself isn’t dangerous, it can cause significant distress and may take several days to weeks to heal on its own if left untreated.

Thrombosed hemorrhoids are a specific, and often more painful, type of external hemorrhoid. When a blood clot forms inside the swollen vein, it leads to distinct, sometimes alarming symptoms. Recognizing these early can help you decide when to seek treatment or medical advice.
Here are the hallmark signs to help you assess your situation:
One of the first and most noticeable symptoms of a thrombosed hemorrhoid is sudden, intense pain in the anal area. Unlike regular external hemorrhoids, this pain doesn’t come and go, it’s constant and often worsens with movement, sitting, or bowel movements.
A thrombosed hemorrhoid typically forms a firm, tender bump or swelling near the anal opening. This lump may feel like a pea or marble and is often painful to touch.
Due to the presence of a blood clot, the lump may appear blue or purplish in color. This discoloration is a key sign that you’re dealing with a thrombosed hemorrhoid rather than a typical swollen vein.
Thrombosed hemorrhoids often cause discomfort with basic movements, especially when sitting or walking. The increased pressure on the clot can make daily activities difficult without relief measures.
While some hemorrhoids may bleed, thrombosed ones usually don’t bleed unless the skin breaks open. Instead, you’ll feel intense pressure and fullness in the area due to the trapped clot.
Rapid swelling in the anal area is another red flag. The clot may form and enlarge within hours, which explains why many people describe the onset of symptoms as sudden and severe.
Not all creams are created equal. See if hydrocortisone is safe for thrombosed hemorrhoids or if you need something stronger.
Thrombosed hemorrhoids don’t appear out of nowhere; they’re usually the result of pressure, poor circulation, or injury to the sensitive veins around the anus. If you’re wondering what caused yours to suddenly become so painful, understanding the triggers can help prevent future flare-ups and support smarter self-care.
Let’s break down the common causes in a practical, easy-to-follow way:
Yes, straining on the toilet is one of the most common causes of thrombosed hemorrhoids. When you push too hard, you create pressure that can cause a small blood vessel in an external hemorrhoid to rupture, forming a clot. Chronic constipation or even lifting something heavy can have a similar effect.
Absolutely. Prolonged sitting, especially on hard surfaces or toilets, limits blood flow in the rectal area. This stagnation increases the risk of a clot forming in an already irritated hemorrhoid. That’s why truck drivers, office workers, and new moms often report more issues.
Yes. Pregnancy naturally puts extra pressure on the pelvic veins, and during childbirth, especially vaginal delivery, the pushing stage can cause blood to pool and clot in external hemorrhoids. It’s one of the most common postpartum complaints.
Heavy lifting, weight training, or intense exertion (without proper core engagement) can increase intra-abdominal pressure. This sudden spike in pressure may rupture small veins, leading to clot formation. Athletes and gym-goers are not immune.
Surprisingly, yes. Rubbing or wiping too hard, frequent scratching due to itching, or anal trauma from rough cleansing or anal intercourse can damage delicate vessels. This damage can cause blood to collect and clot within an external hemorrhoid.
While not always the first cause considered, some people may be genetically predisposed to weaker vein walls or clotting tendencies. If you have a family history of hemorrhoids or vascular conditions, your risk of developing thrombosed hemorrhoids may be higher.
Passing stool with a thrombosed hemorrhoid can feel impossible. Learn how to ease the pain and avoid worsening the clot.
A thrombosed hemorrhoid usually lasts 7 to 21 days, depending on the size of the clot and how quickly your body heals. In many cases, the pain peaks within the first 48 to 72 hours, then gradually improves as the clot is reabsorbed or the swelling subsides.
Smaller hemorrhoids may resolve on their own with conservative care, like sitz baths, gentle hygiene, and topical relief, within a week. However, larger or more painful clots can take two to three weeks to fully shrink.
If the pain persists after a few days or if the swelling doesn’t subside after two weeks, consult a healthcare provider. In some cases, minor surgical drainage may be necessary to remove the clot and expedite recovery.
Healing a thrombosed hemorrhoid involves reducing pain, encouraging clot reabsorption, and preventing recurrence. While these swollen, clot-filled
external hemorrhoids can be extremely uncomfortable, many improve with proper at-home care and, in some cases, minor medical intervention.
Here’s how to support healing safely and effectively:
Soaking in a warm sitz bath for 15–20 minutes, several times a day, increases blood flow to the area and promotes the natural breakdown of clots. It also soothes inflammation, relieves itching, and helps keep the area clean.
Topical numbing creams with lidocaine provide targeted relief from intense discomfort. That’s where curated relief options like Revivol-XR can make a difference. Their range of doctor-recommended creams, soaks, and cleansing products is explicitly formulated for hemorrhoidal care, including thrombosed types, without harsh additives. Many users report faster comfort and improved healing with consistent use.
Apply an ice pack wrapped in a soft cloth for 10–15 minutes at a time. This constricts blood vessels, reduces swelling, and eases pain, especially in the early stages of thrombosis.
After bowel movements, gently cleanse with a fragrance-free cleansing lotion or warm water, rather than dry toilet paper. Revivol-XR’s Hygienic Cleansing Lotion, infused with aloe and witch hazel, is ideal for daily use and prevents further irritation.
Straining makes thrombosed hemorrhoids worse. Stay hydrated, eat high-fiber foods (such as fruits, vegetables, and whole grains), and consider a pregnancy-safe or gentle fiber supplement. Soft, regular bowel movements are key to recovery.
If the pain doesn’t improve after 72 hours, or if the clot becomes larger or more inflamed, a doctor may recommend incision and drainage. This simple outpatient procedure offers instant relief for hemorrhoids by removing the clot.
Avoid prolonged sitting. Elevate your legs when resting and wear loose, breathable clothing. These habits reduce pressure on the rectal area and encourage better blood flow.
Healing a thrombosed hemorrhoid takes time, but the right approach can ease discomfort and support recovery. The clot inside the swollen vein typically reabsorbs on its own within one to two weeks. During this time, your focus should be on comfort, circulation, and preventing further strain.
Here’s what helps promote healing:
While the body usually breaks down the clot naturally, warm sitz baths and proper rest can help ease inflammation and speed up the healing process. Avoid activities that put direct pressure on the area, like extended periods of sitting or heavy lifting.
To prevent worsening the thrombosis, maintain regular bowel habits. A fiber-rich diet, good hydration, and gentle movement (like walking) help reduce pressure in the rectal area. Avoid straining at all costs.
For many, targeted care products can make a difference. Revivol-XR offers clinically formulated treatments that support comfort and recovery. Their product line, which includes Hemorrhoid creams, botanical cleansers, and soothing soaks, can be a smart addition to your healing toolkit when OTC remedies aren’t enough.
If the hemorrhoid becomes larger, more painful, or shows signs of infection (like pus or spreading redness), seek medical advice promptly. In some cases, minor in-office procedures can offer quicker resolution.

Yes, most thrombosed hemorrhoids do heal on their own. The body will reabsorb the blood clot within a couple of weeks. During this time, it is helpful to alleviate discomfort by using sitz baths, ointments, or pain relievers. However, if you experience severe symptoms, you may require medical assistance to ensure a successful recovery.
See a healthcare provider if a thrombosed hemorrhoid gives you severe pain or if you have rectal bleeding. If you experience persistent swelling or notice signs of infection, such as a fever, seek medical attention immediately. Getting help fast can stop problems and help you get the right treatment for your hemorrhoids and bleeding. This will keep you safe from more complications.
Diagnosis starts with a physical exam. The doctor checks the anal canal and feels for any lumps or swelling. Sometimes, additional tests such as sigmoidoscopy or colonoscopy may be necessary to rule out other potential health issues. In most cases, clear symptoms are enough for the diagnosis.
Treatment options for this include pain relievers, ointments, and sitz baths for mild issues. If you have severe pain, then an external thrombectomy can help. This simple procedure removes clots and gives relief. Surgery, like hemorrhoidectomy, is only for the most extreme cases when other ways do not work and something more invasive is needed.
To help prevent thrombosed hemorrhoids, it is recommended to drink plenty of fluids daily. Eat high-fiber foods to help your bowel movements be softer and easier. Try to exercise regularly, as this helps prevent constipation. Do not strain or sit for extended periods when using the bathroom. This will help protect the blood vessels in that area.
