Swelling from the anus to the perineal area?


Hello, doctor.
When I palpate the perineal area from the direction of my buttocks, I notice a slight protrusion (similar to a line).
It does not hurt when I press on it, and I cannot feel any foreign object present, but it becomes more swollen during an erection.
Is this normal? I have a long-standing issue with constipation, so I tend to strain during bowel movements.
I'm worried that this might have caused some problems over time, and I'm unsure if there is an issue with my rectum, but I generally do not feel any pain.
Thank you.

Hello, this should be the normal structure of the perineum.
If there is redness, swelling, heat, or pain, it may indicate inflammation.

More Info


Swelling from the anus to the perineum can be concerning, especially when accompanied by changes in sensation or discomfort. Based on your description, it seems you are experiencing a swelling or protrusion in the perineal area that is not painful and does not feel like a foreign object. This could be related to several potential causes, particularly given your history of constipation and straining during bowel movements.


Possible Causes of Swelling
1. Hemorrhoids: One of the most common causes of swelling in the anal and perineal area is hemorrhoids, which are swollen veins in the lower rectum and anus. They can be internal or external and may become more pronounced during activities that increase abdominal pressure, such as straining during bowel movements.

2. Perineal Abscess: Although less common, a perineal abscess can occur due to infection, leading to localized swelling. This typically would be accompanied by pain, redness, and possibly fever, which you do not report.

3. Skin Tags: After repeated straining, skin tags can develop around the anal area. These are benign and usually painless, but they can become more noticeable during an erection due to increased blood flow.

4. Prolapse: In some cases, particularly with chronic constipation, there may be a rectal prolapse where part of the rectum protrudes through the anus. This condition can be more pronounced during straining or physical exertion.

5. Lymphatic or Vascular Issues: Swelling can also arise from lymphatic drainage issues or vascular conditions affecting blood flow in the area.


Concerns and Recommendations
Given that you have a history of constipation and are experiencing this swelling, it is essential to address both the symptoms and the underlying cause. Here are some recommendations:
- Dietary Changes: Increasing fiber intake can help alleviate constipation. Foods rich in fiber, such as fruits, vegetables, whole grains, and legumes, can promote regular bowel movements and reduce straining.

- Hydration: Ensure you are drinking enough water throughout the day, as proper hydration can help soften stool and ease bowel movements.

- Avoid Straining: If possible, try to avoid straining during bowel movements. This may involve establishing a regular bathroom routine and allowing yourself enough time to relax.

- Physical Examination: It is advisable to consult a healthcare professional for a thorough examination. They can assess the swelling and determine if it is related to hemorrhoids, skin tags, or another condition. A physical examination may include a digital rectal exam or other diagnostic tests if necessary.

- Monitor Symptoms: Keep track of any changes in the swelling, such as increased size, pain, or bleeding. If you notice any of these symptoms, seek medical attention promptly.


Conclusion
While the swelling you describe may not be immediately concerning, it is essential to address your chronic constipation and any potential underlying issues. A healthcare professional can provide a definitive diagnosis and recommend appropriate treatment options. Taking proactive steps to manage your bowel health can help prevent further complications and improve your overall well-being.
