Bumps Around the Anus: STI, Skin Condition or Anal Papillae?

What Are Bumps Around the Anus?

Bumps around the anus do not always indicate an STI. They may occur due to irritation, hormonal changes, skin conditions, benign anatomical variations, or infections. Because many conditions share a similar appearance, symptoms alone cannot confirm the cause. STI testing may help provide clarity when there is potential exposure or persistent symptoms.

Possible causes may include:

• Irritation from hygiene products or clothing
• Anal papillae (benign growths)
• Haemorrhoids or skin tags
• Skin conditions such as folliculitis or dermatitis
• Infection in some cases, including certain STIs
• Friction or shaving effects

Symptoms alone cannot confirm an STI.

When Could Bumps Around the Anus Be Linked to an STI?

Bumps around the anus may sometimes be associated with an STI, particularly if they appear following unprotected sexual contact, including anal or oral-anal contact. Certain infections such as HPV or herpes can cause lesions in the anal area. If you are also experiencing discomfort, our guide on rectal pain after sex may be helpful. However, many other conditions can produce a very similar appearance, so testing is the most reliable way to determine whether an infection is present.

Common Non-STI Causes of Bumps Around the Anus

Anal Papillae

Anal papillae are small, benign, finger-like projections that occur naturally at the junction between the anal canal and the rectum. They are a normal anatomical variation and are not caused by infection.

Haemorrhoids and Skin Tags

Haemorrhoids — swollen blood vessels around the anus — are extremely common and can present as soft, tender lumps. Anal skin tags, which are small flaps of excess skin, often develop following haemorrhoids or local irritation.

Folliculitis

Hair follicles around the perianal area can become inflamed or infected, resulting in small red or white bumps that may resemble spots or blisters.

Contact Dermatitis

Sensitivity to soaps, shower gels, wet wipes, laundry detergent, or even certain toilet paper brands can cause localised irritation, redness, and bumps around the anus.

Molluscum Contagiosum

Whilst technically a viral infection, molluscum contagiosum is not exclusively sexually transmitted and can spread through general skin-to-skin contact or shared towels.

Blocked Glands

Small glands around the anal region can occasionally become blocked, producing cyst-like bumps that may be tender but are generally harmless.

STIs That May Cause Similar Symptoms

HPV (Human Papillomavirus)

HPV is one of the most common STIs and certain strains can cause genital or anal warts. These typically appear as small, flesh-coloured, cauliflower-like growths. For more detail on whether genital warts can be cured, see our dedicated article.

Herpes (HSV)

Herpes simplex virus can cause clusters of small, fluid-filled blisters around the anus, which may burst and form shallow ulcers.

Syphilis

Primary syphilis can cause a single, firm, painless ulcer (known as a chancre) at the site of infection, which can include the anal area.

Chlamydia and Gonorrhoea

Whilst chlamydia and gonorrhoea primarily cause discharge and discomfort rather than bumps, rectal infections with these bacteria can occasionally cause localised inflammation or swelling. If you have noticed anal discharge after sex, this may also warrant further investigation.

How STI Symptoms Can Overlap With Other Conditions

Genital warts caused by HPV can look very similar to anal papillae or skin tags. Herpes blisters can resemble folliculitis. A syphilis chancre can be mistaken for a minor abrasion or cyst.

This overlap is precisely why visual self-diagnosis is unreliable. Even experienced clinicians may require laboratory testing to distinguish between certain conditions.

When STI Testing May Be Sensible

Consider STI testing if:

• Bumps or lesions have appeared following a new sexual partner
• There has been unprotected vaginal, anal, or oral sexual contact
• A sexual partner has been diagnosed with an STI
• Symptoms are persistent, recurring, or worsening
• There are additional symptoms such as discharge, pain, or general malaise
• You are experiencing anxiety about a possible exposure and would like reassurance

A full STI screen can test for multiple infections simultaneously, offering broader reassurance.

Frequently Asked Questions

Can bumps around the anus be normal?

Yes, bumps around the anus can be entirely normal. Anal papillae, skin tags, haemorrhoids, and minor follicular irritation are all common and benign.

Do bumps around the anus always mean an STI?

No. Many conditions unrelated to STIs can cause bumps around the anus. Skin irritation, benign growths, and dermatological conditions are among the most common causes.

Should I get tested if the bumps disappear on their own?

If there has been a recent sexual exposure or a change in partners, testing may still be worthwhile even if symptoms resolve.

When to Seek Medical Advice

Consider seeking advice from an appropriate healthcare service if you experience:

• Severe or worsening pain around the anus
• Open sores or ulcers that are not healing
• Fever or general malaise alongside anal symptoms
• Rapidly spreading rash or lesions
• Significant bleeding from the anal area
