There is an unusual sensation in the anus?


Hello Doctor, I had a colonoscopy on March 27, during which two polyps (0.3 cm and 0.8 cm) were removed.
Both were diagnosed as benign colorectal polyps, and there was no inflammation in the colon.
I was advised to have another colonoscopy in three years.
However, I have been experiencing a strange sensation in my anus, feeling bloated and tight, which persists throughout the day after bowel movements.
I notice that moving around helps alleviate the sensation.
The doctor mentioned that this could be related to internal hemorrhoids, but stated that my internal hemorrhoids are not severe and are quite mild.
Is this normal? Thank you.

After undergoing a colonoscopy, it is not uncommon for patients to experience some discomfort or unusual sensations in the anal and rectal area. In your case, you mentioned feeling a persistent sensation of fullness or tightness, particularly after bowel movements, which can be concerning. However, it's important to understand that these sensations can be attributed to several factors related to the procedure and your individual anatomy.

Firstly, during a colonoscopy, the insertion of the scope can cause temporary irritation to the lining of the colon and rectum. Even though the procedure is generally safe and well-tolerated, some patients may experience residual discomfort due to minor trauma or irritation. This discomfort usually resolves within a few days to a week. Since you had two polyps removed, it is possible that the area around the removal sites is still healing, which could contribute to the sensations you are experiencing.

The fact that your polyps were benign and that there was no inflammation noted during the procedure is reassuring. It suggests that there are no immediate concerns regarding your colon health. The tightness and fullness you feel could also be related to the presence of hemorrhoids, which you mentioned were diagnosed as mild. Hemorrhoids can cause sensations of pressure or discomfort, especially during bowel movements, and can take some time to resolve after treatment.

It's also worth noting that the sensation of discomfort can be influenced by factors such as diet, hydration, and bowel habits. If you are experiencing changes in your bowel movements, such as increased frequency or straining, this could exacerbate any discomfort associated with hemorrhoids or the healing process after polyp removal.

In terms of what you can do moving forward, here are some recommendations:
1. Dietary Adjustments: Ensure you are consuming a high-fiber diet to promote regular bowel movements and prevent constipation. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying well-hydrated is also crucial.

2. Gentle Exercise: Engaging in regular physical activity can help stimulate bowel function and may alleviate some of the discomfort you are feeling.

3. Follow-Up with Your Doctor: Since your symptoms have persisted, it would be wise to follow up with your healthcare provider. They can perform a physical examination to assess for any underlying issues, such as residual hemorrhoids or other conditions that may be contributing to your discomfort.

4. Monitor Symptoms: Keep track of your symptoms, including any changes in bowel habits, the severity of discomfort, and any new symptoms that may arise. This information can be helpful for your doctor during your follow-up visit.

5. Consider Over-the-Counter Remedies: If you are experiencing significant discomfort, over-the-counter treatments for hemorrhoids, such as topical creams or suppositories, may provide relief. However, it is advisable to consult with your doctor before starting any new medications.

In summary, while it is not unusual to experience some discomfort after a colonoscopy, especially following the removal of polyps, persistent symptoms should be evaluated by a healthcare professional. Your doctor can provide reassurance, rule out any complications, and suggest appropriate management strategies to help alleviate your discomfort. Remember, open communication with your healthcare provider is key to addressing any concerns you may have regarding your health.
