Subcutaneous protrusions around the anus?


Hello Doctor: Thank you for your previous response! Recently, I noticed a raised area under the skin around the right side of my anus while showering.
It doesn't seem to be an external hemorrhoid.
The left side is smooth, but pressing on it causes pain, although there is no significant discomfort otherwise and no discharge.
Could this be the internal hemorrhoid diagnosed earlier, or could it be something else, like an anal abscess? I am still experiencing discomfort in the anal area, but there is no blood in my stool.
Thank you!

Based on your description, a thrombosed external hemorrhoid or an anal abscess are both possible, but without a personal examination, I cannot provide a definitive answer.
I recommend that you seek medical attention at a hospital as soon as possible.
If it is an anal abscess, delaying treatment could be life-threatening.

Understanding subcutaneous bumps around the anus can be concerning, and it's important to approach this issue with careful consideration of potential causes and implications. Based on your description, it sounds like you have noticed a bump near the anus that is painful when pressed but does not produce any discharge. This could be related to several conditions, and I will outline some possible explanations.

1. Hemorrhoids: You mentioned that you have been diagnosed with internal hemorrhoids. While internal hemorrhoids typically do not cause external bumps, they can sometimes lead to the formation of external hemorrhoids or thrombosed hemorrhoids, which can present as painful lumps around the anal area. Thrombosed hemorrhoids occur when a blood clot forms within the hemorrhoid, leading to swelling and discomfort.

2. Anal Abscess: An anal abscess is a collection of pus that can occur due to infection in the anal glands. This can cause a painful lump near the anus, and while you mentioned there is no discharge, it is still possible for an abscess to be present without visible pus. If the abscess is deep, it may not drain externally, but it can still cause significant discomfort.

3. Fistula: An anal fistula is an abnormal connection between the anal canal and the skin near the anus. It can develop as a complication of an abscess. Symptoms may include pain, swelling, and sometimes discharge, but in some cases, it may not be immediately apparent.

4. Skin Tags: Sometimes, after the resolution of hemorrhoids or other anal conditions, skin tags can form. These are benign and typically painless unless they become irritated. However, they can sometimes be mistaken for more serious conditions.

5. Other Conditions: There are other potential causes for bumps around the anus, including warts (which can be caused by the human papillomavirus), cysts, or even dermatological conditions like folliculitis or dermatitis.

Given that you are experiencing discomfort and pain, it is essential to consult a healthcare professional for a thorough examination. They may perform a physical examination and possibly recommend imaging studies or other diagnostic tests to determine the exact cause of the bump.
In the meantime, here are some general recommendations to manage discomfort:
- Warm Sitz Baths: Soaking in warm water can help relieve pain and discomfort in the anal area.

- Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce pain and inflammation.

- Avoid Straining: Ensure that you are not straining during bowel movements, as this can exacerbate hemorrhoids and other anal conditions. A high-fiber diet and adequate hydration can help maintain regular bowel movements.

It is crucial to avoid self-diagnosing or treating the condition without professional guidance, especially since you have ongoing discomfort. If the bump persists, worsens, or if you develop new symptoms such as fever, increased pain, or changes in bowel habits, seek medical attention promptly. Your healthcare provider will be able to provide a definitive diagnosis and appropriate treatment options tailored to your specific condition.

If it is an anal canal issue, you should be able to feel a firm subcutaneous tissue between the two areas. Based on your description, it seems more like a small abscess, likely a benign lesion such as an epidermal inclusion cyst. It may be advisable to try antibiotics first.
