Midnight Rectal Pain: Your Symptoms and Concerns - Gastroenterology and Hepatology

Experiencing pain in the rectum at night and difficulty passing stool?


Hello, doctor.
Occasionally, I wake up in the middle of the night with pain deep inside my buttocks, likely in the rectal area.
The pain is severe enough to keep me awake.
When I try to use the bathroom, I can hardly pass anything; sometimes I can squeeze out a small amount of stool, but it's not hard—just normal consistency.
Occasionally, there is a slight sensation of mucus as well.
It takes a long time for the discomfort to subside, but it usually doesn't happen during the day.
It occurs infrequently, about once a month, and it's unpredictable.
Could this be a sign of colorectal cancer, or is it something else? I find it difficult to ask the doctor about it when I have no symptoms during the visit.
Thank you for your help.

Hello, sir: It doesn't seem very much like colorectal cancer, but you can visit the gastroenterology clinic for a sigmoidoscopy to examine the lower part of the colon (approximately 50-60 cm deep) for your peace of mind.

Midnight rectal pain can be a concerning symptom, and it's understandable that you're worried about what it might indicate. Based on your description, it sounds like you are experiencing pain in the rectal area that awakens you at night, along with difficulty passing stool and occasional mucus discharge. While I cannot provide a diagnosis, I can help you understand some potential causes and the importance of seeking medical attention.

First and foremost, it's essential to recognize that rectal pain can arise from various conditions, some of which may be benign while others could be more serious. Common causes of rectal pain include:
1. Hemorrhoids: Swollen blood vessels in the rectum or anus can cause pain, especially during bowel movements. They can also lead to bleeding and discomfort.

2. Anal Fissures: Small tears in the lining of the anus can result in sharp pain during and after bowel movements. This pain can be severe and may cause you to avoid going to the bathroom.

3. Constipation: Difficulty passing stool can lead to straining, which may cause pain and discomfort in the rectal area. Even if your stools are not hard, infrequent bowel movements can still lead to discomfort.

4. Infections or Inflammatory Conditions: Conditions like proctitis (inflammation of the rectum) or infections can cause pain and may be accompanied by mucus discharge.

5. Pelvic Floor Dysfunction: Issues with the muscles and nerves in the pelvic area can lead to pain and difficulty with bowel movements.

6. More Serious Conditions: While it's less common, rectal pain can sometimes be associated with more serious conditions, including colorectal cancer, especially if accompanied by other symptoms such as significant changes in bowel habits, unexplained weight loss, or blood in the stool.

Given that your symptoms occur primarily at night and are infrequent, it may be challenging to pinpoint the exact cause without a thorough evaluation. However, the fact that you are experiencing pain that disrupts your sleep is significant. Sleep disturbances can exacerbate stress and anxiety, which may further complicate your symptoms.

It's crucial to consult a healthcare professional about your symptoms. When you visit your doctor, consider the following tips to help communicate your concerns effectively:
- Keep a Symptom Diary: Note when the pain occurs, its intensity, any associated symptoms (like mucus or changes in bowel habits), and any potential triggers (such as diet or stress).

- Be Honest About Your Fears: It's okay to express your concerns about serious conditions like colorectal cancer. This can help your doctor understand your anxiety and guide their evaluation.

- Ask Questions: Don't hesitate to ask your doctor about potential causes of your symptoms and what tests might be necessary to rule out serious conditions.

In summary, while your symptoms could be related to common and less serious conditions, it is essential to seek medical advice to rule out any serious issues. Early diagnosis and treatment can significantly improve outcomes and alleviate your concerns. Remember, your health is important, and addressing these symptoms with a healthcare provider is a proactive step toward understanding and managing your condition.
