A lump has appeared near the anus?


Hello Dr.
Ke, recently I have noticed a painful lump outside my anus, which feels quite hard.
Previously, I experienced bleeding when having hard bowel movements (the toilet paper showed bright red blood).
Last week, there was more bleeding (blood mixed in the toilet water), but it returned to normal after two to three days.
Now, this week, the lump outside my anus has started to hurt.
I would like to know what these symptoms could indicate.
(I have done some research but I'm unsure if it's hemorrhoids or an anal fistula.)

Based on your description, it seems more like the typical symptoms of an anal fissure, which include pain during bowel movements accompanied by slight bleeding.
The common causes are often constipation or diarrhea.
The fundamental treatment is to improve bowel habits, along with warm sitz baths.
You can also purchase hemorrhoid suppositories at the pharmacy for relief.
If symptoms persist without improvement, it is advisable to consult a physician for further evaluation.

Hello! Based on your description, it sounds like you may be experiencing symptoms that could be related to either hemorrhoids or an anal fistula. Let’s break down these two conditions to help you understand what might be going on.

Hemorrhoids are swollen veins in the lower rectum or anus, similar to varicose veins. They can be classified into two types: internal and external. Internal hemorrhoids occur inside the rectum and are usually not visible or painful, but they can cause bleeding during bowel movements, which may explain the bright red blood you noticed on the toilet paper and in the water. External hemorrhoids, on the other hand, develop under the skin around the anus and can become painful, especially if a blood clot forms within them. The hard, painful lump you mentioned could be an external hemorrhoid that has become thrombosed (clotted), leading to increased pain and discomfort.

Anal fistulas, on the other hand, are small tunnels that can develop between the end of the bowel and the skin near the anus. They often occur as a result of an infection in the anal glands, leading to an abscess. Symptoms of an anal fistula can include pain, swelling, and discharge of pus or blood. The presence of a hard lump and pain, especially if associated with discharge, could suggest the presence of a fistula.

Given your symptoms of a hard, painful lump and the history of bleeding, it is essential to consult a healthcare professional for a proper diagnosis. They may perform a physical examination and possibly recommend further tests, such as an anoscopy or ultrasound, to determine the exact nature of the lump and the underlying cause of your symptoms.

In terms of treatment, hemorrhoids can often be managed with conservative measures such as dietary changes (increasing fiber intake), topical treatments, and warm baths. In more severe cases, medical procedures may be necessary. Anal fistulas typically require surgical intervention to heal properly, as they do not resolve on their own.

It’s important to address these symptoms promptly, as untreated conditions can lead to complications. If you experience severe pain, persistent bleeding, or any signs of infection (such as fever or increased swelling), seek medical attention immediately.

In summary, while both hemorrhoids and anal fistulas can present with similar symptoms, the treatment and management strategies differ significantly. A healthcare provider will be able to give you a definitive diagnosis and appropriate treatment plan based on a thorough examination. Please take care of your health, and don’t hesitate to reach out to a medical professional for further assistance.
