Types of anal abscess and methods of prevention

The most common type of abscess is the external perianal abscess. This often appears as a painful, boil-like swelling near the anus. It may be red in color and warm to the touch. Anal abscesses that are in deeper tissues are less common and may be less noticeable.

The risk that anal abscess poses is that about 50% of patients with anal abscess develop a complication called a fistula. A fistula is a small channel that makes an abnormal connection between the abscess site and the skin. In some cases, an anal fistula causes continuous drainage. In other cases, the outer part of the opening of the tunnel closes, and results in recurrent anal abscesses.

Anal abscess can have many causes which include:

Anal fissure or tear in the anal canal or infection

Sexually transmitted diseases

Blockage of the anal glands

Risk factors for anal abscesses include:

Colitis

Inflammatory bowel diseases such as Crohn's disease or ulcerative colitis

Diabetes 

Pelvic inflammation

For adults, using a condom during sexual intercourse can help prevent anal abscesses. For infants and young children, frequent diaper changes and proper cleaning during diaper changes can help prevent anal fistulas and perianal abscesses.

Symptoms of Anal Abscesses:

Pain, which is usually constant and throbbing and is worse when sitting down.

Inflammation of the skin around the anus, including swelling, redness, and pain.

Pus Secretion

Constipation or pain during  bowel movements.

Deep anal abscesses may also be associated with:

Fever.

Goosebumps.

Malaise.

But sometimes, high temperature is the only symptom of deep anal abscesses.
