An anal abscess is a painful condition in which a collection of pus develops near the anus. Most anal abscesses are a result of infection from small anal glands. The most common type of abscess is a perianal abscess. This often appears as a painful boil-like swelling near the anus. It may be red in colour and warm to the touch.
Symptoms & Causes
The most common symptoms are Pain, which is usually constant, throbbing, and worse when sitting down, skin irritation around the anus, including swelling, redness, and tenderness, discharge of pus, Constipation or pain associated with bowel movements
An anal abscess can have many different causes like infection of an anal fistula, sexually transmitted infections or blocked anal glands.
Treatment for Anal Abscess
Surgical incision and drainage is the most common treatment for all types of anal abscesses and is usually successful. This can be done in a doctor’s office with local anaesthetic or in an operating room under deeper anaesthesia. Hospitalization may be required for patients prone to more significant infections, such as diabetics or patients with decreased immunity.
About 50% of patients with an anal abscess will develop a complication called a fistula. A fistula is a small tunnel that makes an abnormal connection between the site of the abscess and the skin.
