Anorectal foreign body sensation


Hello, doctor.
I would like to ask about a lump near my anus (I'm not sure if it's a polyp).
I was previously diagnosed with an external hemorrhoid and underwent a minor surgery.
This time, I usually don't feel pain or itching, but sometimes I have a sensation of a foreign body and occasionally feel a slight pain.
My bowel movements are normal and without blood.
Do I need to see a doctor?

When it comes to experiencing a sensation of a foreign body in the rectal area, it is essential to approach the situation with caution and awareness of potential underlying issues. Given your history of external hemorrhoids and previous minor surgery, it is understandable that you might be concerned about any new sensations or discomfort in that area.

Firstly, the sensation of a foreign body or the feeling of something unusual around the anus can be attributed to several factors. It could be related to the presence of hemorrhoids, anal fissures, or even rectal polyps. Hemorrhoids, which are swollen veins in the lower rectum and anus, can sometimes create a feeling of fullness or pressure, leading to the sensation you described. Similarly, anal fissures, which are small tears in the lining of the anus, can cause discomfort and a sensation of something being present, especially during bowel movements.

Rectal polyps, which are growths on the lining of the rectum, can also contribute to a feeling of an abnormal mass or foreign body sensation. While many polyps are benign, some can be precursors to colorectal cancer, making it crucial to monitor any changes in symptoms or sensations.
In your case, since you mentioned that the sensation is not accompanied by pain, bleeding, or significant changes in bowel habits, it may not be an immediate cause for alarm. However, the occasional pain and the sensation of a foreign body should not be ignored. It is essential to consider the following factors when deciding whether to seek medical advice:
1. Duration of Symptoms: If the sensation persists or worsens over time, it is advisable to consult a healthcare professional. Persistent symptoms could indicate an underlying issue that may require further evaluation.

2. Changes in Bowel Habits: While you mentioned that your bowel movements are normal and without blood, any changes in frequency, consistency, or the presence of blood should prompt a visit to the doctor.

3. Associated Symptoms: If you begin to experience additional symptoms such as increased pain, swelling, or any changes in your overall health, it is crucial to seek medical attention.

4. History of Rectal Issues: Given your history of external hemorrhoids and previous surgery, it is wise to have any new symptoms evaluated by a healthcare professional, particularly a gastroenterologist or a colorectal surgeon.

5. Peace of Mind: If you are feeling anxious or concerned about the sensation, it is always better to err on the side of caution. A healthcare provider can perform a physical examination and possibly recommend further diagnostic tests, such as a colonoscopy, to rule out any serious conditions.

In conclusion, while your current symptoms may not seem alarming, it is essential to monitor them closely. If the sensation persists, worsens, or is accompanied by any concerning symptoms, I strongly recommend seeking medical advice. A healthcare professional can provide a thorough evaluation and ensure that any potential issues are addressed promptly, giving you peace of mind and maintaining your overall health.
