Perianal Lumps: Hemorrhoids, Pimples, or Abscess? - Surgery

A perianal lump can be a hemorrhoid, a pimple, or an anal fistula?


Hello, Doctor Yu.
Occasionally, I notice blood on the toilet paper after wiping, but there is no pain.
Recently, I developed a lump about the size of half a coin next to my anus, which is painful.
I experience discomfort when walking, sitting, or riding a bike, especially when there is friction or pressure.
After researching, I thought it might be an external hemorrhoid, but today the pain suddenly stopped, and now there is only a slight pain when I tighten my buttocks.
It seems like it might have burst, as there is now a yellowish-white, slightly gray-green pus without any blood.
Currently, I can walk without pain, but the lump has shrunk by half and is still present.
I am considering going to the pharmacy to buy some ointment and take warm sitz baths.
Could you please advise if this is a pimple, an external hemorrhoid, or possibly an anal fistula? Thank you very much for taking the time to respond!

More Info


Understanding perianal lumps can be quite challenging, especially when symptoms vary and the cause is not immediately clear. Based on your description, it seems you are experiencing a painful lump near the anus, which initially presented with bleeding and has now changed in character. Let's break down the potential causes and what you can do about it.


Possible Causes of Perianal Lumps
1. Hemorrhoids: These are swollen veins in the lower rectum and anus that can cause discomfort, pain, and bleeding. External hemorrhoids can be felt as lumps around the anus and may become painful, especially when sitting or during bowel movements. The fact that you initially saw blood on the toilet paper could suggest this, especially if the bleeding was bright red.

2. Abscess: An anal abscess is a collection of pus that can occur due to infection. Symptoms typically include pain, swelling, and sometimes fever. The presence of yellowish-green pus suggests that there may have been an infection, which aligns with the characteristics of an abscess. The fact that the pain has decreased could indicate that the abscess has started to drain.

3. Pimples or Folliculitis: Sometimes, hair follicles around the anal area can become infected, leading to painful lumps that may resemble pimples. These can also drain pus and may resolve on their own.

4. Fistula: An anal fistula is a small tunnel that can develop between the end of the bowel and the skin near the anus, often following an abscess. If you notice persistent drainage or a lump that does not resolve, this could be a possibility.


Recommendations for Management
Given your symptoms, here are some steps you can take:
- Warm Sitz Baths: Soaking in warm water can help relieve pain and promote drainage if there is an abscess. This is often recommended for hemorrhoids as well.

- Over-the-Counter Treatments: You can consider using topical treatments available at the pharmacy, such as hydrocortisone creams for hemorrhoids or antiseptic ointments for minor skin infections. However, avoid using any products that could irritate the area further.

- Pain Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage discomfort.

- Monitor Symptoms: Keep an eye on the lump. If it continues to shrink and you have no further symptoms, it may resolve on its own. However, if you experience increased pain, fever, or if the lump does not improve, you should seek medical attention.


When to See a Doctor
It is advisable to consult a healthcare professional if:
- The lump persists or increases in size.

- You experience significant pain or fever.

- There is a change in the nature of the drainage (e.g., increased redness, swelling, or foul odor).

- You have any concerns about the nature of the lump or if it recurs.


Conclusion
While it is possible that your symptoms could be due to hemorrhoids or an abscess, the presence of pus and the change in pain levels suggest that an infection might be involved. Self-care measures like warm baths and topical treatments can be helpful, but do not hesitate to seek medical advice if your symptoms do not improve or worsen. A healthcare provider can perform a thorough examination and provide a definitive diagnosis and treatment plan tailored to your needs.
