Middle rectum pain refers to discomfort or pain felt in the central part of the rectum. The rectum is the final part of the large intestine, where stool is stored before being passed out of the body. This pain can range from mild discomfort to severe pain and can be caused by various conditions, ranging from simple issues like constipation to more complex diseases such as inflammatory bowel disease (IBD) or rectal cancer.
In this guide, we will explain the anatomy of the rectum, different types of rectal pain, causes, symptoms, diagnostic tests, non-pharmacological treatments, drugs, surgeries, prevention methods, and when to seek medical attention.
Anatomy of the Rectum
The rectum is about 12 to 15 cm long and connects the sigmoid colon (the last part of the colon) to the anal canal. It is located in the pelvic cavity, and its main function is to store feces until defecation.
Structure
- Layers of the Rectum:
- Mucosa: The inner lining of the rectum that absorbs water and electrolytes.
- Submucosa: Contains blood vessels and nerves.
- Muscularis: This muscle layer contracts to help push out stool.
- Serosa/Adventitia: The outermost layer of the rectum.
- Blood Supply: The rectum is supplied with blood through the superior rectal artery, middle rectal artery, and inferior rectal artery.
- Nerve Supply: The rectum receives nerves from the pelvic splanchnic nerves (parasympathetic) and hypogastric plexus (sympathetic). Sensory nerves help detect the presence of stool.
Types of Rectal Pain
There are various types of rectal pain that can occur:
- Acute rectal pain: Sudden onset, often due to infections, fissures, or trauma.
- Chronic rectal pain: Lasting for more than a few weeks, often due to chronic conditions like hemorrhoids or IBD.
- Referred pain: Pain that originates from another part of the body, such as the lower back, but is felt in the rectum.
- Intermittent rectal pain: Comes and goes, often associated with bowel movements.
Causes of Middle Rectum Pain
- Hemorrhoids: Swollen blood vessels in the rectal area, leading to pain, itching, and sometimes bleeding.
- Anal Fissures: Small tears in the lining of the rectum that cause sharp pain, especially during bowel movements.
- Constipation: Hard stools can stretch and damage the rectal lining.
- Diarrhea: Frequent bowel movements can irritate the rectal area.

- Coccydynia: Tailbone pain that radiates to the rectum.
- Rectal Ulcers: Sores in the rectal lining caused by prolonged constipation or inflammatory conditions.
- Sexually Transmitted Infections (STIs): Infections like herpes, gonorrhea, or chlamydia can cause rectal pain.
- Diverticulitis: Inflammation of small pouches in the colon can extend to the rectum.
- Rectal Prolapse: The rectum slips out of place, causing pain and discomfort.
