Bleeding from a thrombosed external hemorrhoid?


Hello, doctor.
Over a year ago, I had a thrombosed hemorrhoid that healed on its own.
However, it has recurred about six days ago.
For the past six days, I have been applying hemorrhoid cream externally, but I'm not sure if the three bowel movements I had the day before yesterday (which I tried to control the force) contributed to this.
Since yesterday, I've noticed a small amount of blood and itching when wiping, and this morning I found noticeable blood stains on my underwear.
There was also a small amount of blood when I wiped.
Today, the thrombosed hemorrhoid has shrunk (about half its size), and the pain has decreased (though there is still slight pain when touched).
I would like to ask if this bleeding is normal? Is there a risk of infection? Should I consider taking medication as well? Thank you.

Thrombotic external hemorrhoids may rupture during the absorption process, resulting in a small amount of dark blood, similar to bleeding.
If the bleeding does not persist, it is usually not a concern.
However, if the bleeding and pain do not improve, it is important to seek medical treatment promptly.

More Info


Bleeding from thrombosed hemorrhoids can be a concerning and uncomfortable experience. It’s important to understand the causes, potential complications, and appropriate care for this condition.
Thrombosed hemorrhoids occur when a blood clot forms in the external hemorrhoid, leading to swelling, pain, and sometimes bleeding. The bleeding you are experiencing, especially after a bowel movement, can be attributed to the irritation and inflammation of the hemorrhoid. When you strain during bowel movements, it can exacerbate the condition, leading to further bleeding. The fact that you have noticed a decrease in the size of the thrombosed hemorrhoid and a reduction in pain is a positive sign, indicating that the body may be resolving the clot and inflammation.

However, the presence of blood, especially if it is bright red, can indicate that the hemorrhoid is still irritated or that there may be a small tear in the surrounding tissue. It’s also possible that the straining during bowel movements could have caused a fissure, which can lead to additional bleeding. While minor bleeding can be normal in this context, it’s essential to monitor the situation closely.

In terms of infection risk, thrombosed hemorrhoids themselves are not typically associated with a high risk of infection. However, if there is significant bleeding, swelling, or if you notice increasing pain, fever, or discharge that appears unusual, it could indicate an infection or other complications that would require medical attention.

As for treatment, continuing to use topical hemorrhoid medications can help alleviate symptoms. These medications often contain ingredients that reduce inflammation and provide pain relief. Additionally, it is crucial to maintain a soft stool to minimize straining during bowel movements. This can be achieved by increasing dietary fiber intake, staying hydrated, and possibly using stool softeners if necessary.
If the bleeding persists or worsens, or if you experience severe pain, it is advisable to consult a healthcare professional. They may recommend further evaluation, which could include a physical examination or possibly a referral to a specialist, such as a gastroenterologist or a colorectal surgeon, for more comprehensive management.

In summary, while some bleeding from thrombosed hemorrhoids can be normal, it is essential to monitor your symptoms closely. Maintaining a soft stool and using topical treatments can help manage your condition. If you have any concerns about the severity of your symptoms or if they do not improve, seeking medical advice is the best course of action.
