Various factors can cause one or more bumps on the anus. These include anal fissures, hemorrhoids, and skin tags.
The anus is the endpoint of the gastrointestinal (GI) tract. It is where stool exits the body.
People may wish to better understand their symptoms by touching the anus and surrounding area. It is crucial to wash the hands before and after doing so to prevent the spread of bacteria.
Anal fissures are small cuts or tears in or on the anus. They may result from passing hard stool, which can tear the delicate skin of the anus.
When a fissure starts to heal, it can form a skin tag that may feel like a lump.
An anal fissure may cause:
- rectal bleeding, often after passing hard stool
- a burning or tearing sensation during a bowel movement
- pain, which may last
several daysafter passing hard stool

Hemorrhoids are enlargements of anal tissue. They result from swollen veins in the rectum and anus. These enlargements may be internal or external.
Symptoms of hemorrhoids include:
- painless rectal bleeding
- itching in the anal region
- pain or discomfort in the anal area, especially during and after bowel movements
- swelling around the anus that may form a lump
Pregnant people and older adults have a higher risk of developing hemorrhoids.

Anal skin tags are collections of excess skin around the anus. A skin tag may feel like a small lump or buildup of tissue.
These tags can occur due to hemorrhoids or healing anal fissures.
They typically do not cause symptoms. However, excessively rubbing the tags can cause discomfort or mild bleeding. Larger tags can also cause other symptoms.

An anal pimple may feel like a soft, fluid-filled bump. Irritation can cause these pimples to become sore or otherwise uncomfortable.
It is important not to pop these pimples, as doing so can result in infection.

- pain or frequent discomfort in the rectal area, particularly with bowel movements
- pus-like discharge from an anal lump
- symptoms of a systemic infection, such as:

A doctor will ask about a person’s symptoms and perform a visual and physical examination of the anal opening.
The doctor may be able to identify the issue based on visual inspection alone, or they may need a small tissue sample for analysis.
The doctor may recommend additional tests, such as a sigmoidoscopy or colonoscopy. These procedures involve inserting a thin, lighted tube with a camera into the anal canal to look for signs of health issues.
A colonoscopy can help determine whether any abnormalities extend throughout the lower GI tract.
