1. What is a perianal hematoma?

Perianal Hematoma, often mistakenly called external haemorrhoids, refers to an outer anal lump that consists of a pool of blood under the surface of the skin. Generally, a bleeding or ruptured vein caused by a minor trauma leads to perianal hematoma. The outer lump near anus can vary in size, ranging from the size of a centimeter to the size of a tennis ball.

Finding a lump near anus can be quite alarming, but try not to worry as it is easily identifiable.

Signs of a perianal hematoma lump include the following:

  • Dark blue blister/ bruise under the skin around your anal opening
  • Mild-to-severe levels of perianal pain
  • The occurrence of blood while passing stools

Perianal hematoma treatment depends on the severity of the anal lump. If a blood clot is formed in the region, a general surgeon will remove it during an in-office procedure. Most often, a perianal hematoma can resolve itself in due course. A common misconception is that perianal hematoma and prolapsed haemorrhoids, are the same. While having very similar symptoms, a prolapsed haemorrhoid is a collection of a pool of blood inside the anus. It is never located outside, unlike a perianal hematoma.

In any case, it is essential to seek out proper medical attention for perianal hematoma. Consulting a general surgeon can help you identify your perianal pain. In addition to this, a full body health checkup once a year can help you understand your health and the areas that require improvement. You can chat with a doctor on or our app, or you can avail a comprehensive health check up or a specific condition-based health package depending on your age, gender, and existing medical conditions. Your samples will be collected at home and analysed by trained medical professionals. The reports will be sent across to you in just 48 hours, after which you can follow up with your doctor from the comfort of your home.

2. What causes perianal hematoma?

The human anus constitutes different kinds of tissues, such as:

  • blood vessels
  • mucous membranes
  • nerves
  • lymph nodes

A lump near anus can form due to irritation, injury, infection, or blockage in the anus. To be precise, anything that adds pressure to your anal veins can cause a perianal hematoma lump to appear. Not only do perianal hematoma and hemorrhoids carry similar symptoms, but they also share the same causes. It is essential to understand the differences between both of these conditions, a significant factor being the location of the lump. Consulting a general surgeon will help you learn about your body condition better.

The causes of perianal hematoma lump include:

  • Constipation: Constipation:> When a person is constipated, they’re more likely to pass dry, hard stools, and have infrequent bowel movements. Irregular bowel movements can add too much pressure on your anal veins, therefore causing them to break and form an anal lump.
  • Excessive coughing: Severe coughing can cause ruptured anal veins. Damaged veins leads to perianal discomfort and can create a painful lump around anus.
  • Pregnancy: With fast foetal growth, pregnant women have a higher risk of developing a perianal hematoma lump. The added stress and pressure on the anal veins causes them to get damaged over time. While delivering the baby, increased pressure around the anal region can also stimulate the formation of a lump next to anus.
  • Medical procedures: Rectal examinations that involve a scope (a thin, flexible viewing instrument) can also increase your risk of developing a small lump on anus, if not performed correctly.
  • Lifting heavy weights: Lifting heavy objects, especially heavy objects you’re not used to lifting, can put pressure on your anal region, causing perianal discomfort and develop an anal lump.
  • Inactive/ sedentary lifestyle: Not moving your body and sitting for long hours without a break can increase your risk of developing a perianal hematoma lump.

3. Diagnosing perianal hematoma

While it’s not a significant cause for concern, if you feel/ notice anal discomfort or a hard, small lump on anus, talk to a general surgeon to get it examined. A general surgeon can suggest or provide treatments that can address your anal lump or its underlying cause.

Firstly, your doctor will understand your symptoms and ask questions about your medical history. Next, your doctor will perform a physician exam to diagnose perianal hematoma lump. During the examination, the doctor will use gloved fingers to feel the nature of the anal lump.

Do keep in mind that diagnosing a perianal hematoma (outer lump near anus) is much easier and less invasive than diagnosing prolapsed hemorrhoids, (lump inside anus). Thus, if you have a lump outside anus, you will not require a colonoscopy or other invasive diagnostic procedures.

4. What are the kinds of perianal hematoma treatment?

Perianal hematoma treatment depends on the severity of the lump next to anus. In less severe cases, self-care and over-the-counter medications can help in the healing process. However, in more severe anal lumps, an incision and evacuation procedure may need to be done. A perianal hematoma lump can heal on its own over a couple of weeks, if left alone.

Here are the different methods to treat a perianal hematoma.


Early treatment of perianal hematoma can help mitigate the pain that may develop over time. Here are a few anus pain home remedies that can help relieve anal discomfort:

  • Cold compresses: A cold compress is an ice pack or wet washcloth that can help reduce swelling and relieve pain in the infected hematoma lump.
  • Usage of cushion/ pillow while sitting: As previously mentioned, sitting for long hours without a break can be detrimental to your anal veins. If you have an anal lump, it is advisable to sit on a cushioned surface to avoid further damage.
  • Include more fiber in your diet: Rich sources of fiber include fruits and vegetables. Consuming a diet rich in fibre can help reduce constipation and ensure healthy bowel movements.
  • Avoiding activities that add pressure to your anal region, such as, running, jogging, and weightlifting.
  • Consume a balanced diet: Eating foods that help in the healing process of your perianal pain can do wonders. Consider including the following foods/ nutrients into your diet:

-Fruits and vegetables to encourage frequent bowel movements
-A liquid diet to promote the excretion process
-More protein-rich foods to encourage the healing process of the anal lump


There aren’t any specific medications that cater only to treating perianal hematoma. However, if you experience severe anal discomfort, the doctor may suggest/ recommend taking over-the-counter pain medications.


Depending on the size and severity of your perianal hematoma lump, the general surgeon may recommend performing an in-house procedure to drain the lump near anus. If a blood clot is formed, the general surgeon will numb the area with anesthesia, cut the anal lump, and evacuate the blood clot. This medical procedure is simple and effective as it provides instant relief for the patients. The wound closes after a day or two, and the patients are required to keep the anal region dry and clean.

If you are experiencing anal hardness or perianal pain, consult with a general surgeon to understand what kind of procedure you need to treat perianal hematoma effectively.

5. Consulting a doctor for perianal hematoma

Perianal hematoma can be effectively managed and treated. The right diagnosis is the key to receiving appropriate perianal hematoma treatment.
