This article discusses anal and rectal abscesses, also called boils.

It also goes over what causes them and how they are treated.

By contrast, perirectal abscesses tend to form in deeper tissues and are often more felt than seen.

Of the two types, a perirectal infection tends to be more serious.

These may indicate a systemic infection that has spread from the site of the abscess into the bloodstream.

Without proper treatment, systemic infection of this sort can lead tosepsis, toxic shock, and even death.

Abscesses are triggered by an infection, so they feel warm and are painful when touched.

The pain sparked by an abscess tends to worsen over time.

A hemorrhoid is an enlarged vein that forms inside the rectum or on the anus.

During the physical exam, your healthcare provider will want to ascertain whether the mass is an abscess orhemorrhoid.

The two conditions can usually be differentiated by the presentation of symptoms.

An abscess will also not respond to standardhemorrhoid treatment.

Other tests may be ordered if IBD, HIV, or diabetes is suspected, including blood tests andcolonoscopy.

Treatment

Anorectal abscesses rarely go away on their own or resolve solely withantibiotic therapy.

Some of the extracted pus may be sent to the lab to identify the causal bacterium.

Wash lightly with soap but avoid alcohol or hydrogen peroxide, which can slow healing.

If needed, pad the wound with gauze or a maxi pad.

The drainage of an abscess will provide almost immediate relief.

While there may be some pain after the procedure, it will usually be mild by comparison.

Can I drain a boil myself?

Do not venture to drain a boil yourself.

What looks like a small boil, or abscess, could be a much deeper and extensive infection.

Can the Abscess Come Back?

An anal abscess can recur.

Summary

An anal abscess is a pus-filled lump that forms on or around the anus.

It is because of infection with bacteria.

Abscesses usually don’t go away on their own and need to be drained by a healthcare provider.

Untreated abscesses can lead to the development of an anal fistula, which may require surgery to repair.
