Anal abscesses can be extremely painful and usually occurs when pus develops near the anus. They are usually caused by infections in the anal glands. Perianal abscess is the most common type of anal abscess. It looks like a painful boil swelling near the anus. It will be warm and almost reddish in colour.
Perianal abscess can be caused by anal fissures, infections due to tear in the anal canal, STDs, blockages in anal glands etc. The most common symptoms associated with perianal abscess are pain, due to which it becomes difficult to sit, skin irritation in anus leading to redness, swelling and tenderness, pus, constipation, and in extreme cases fever and chills.
Perianala abscess surgery is not really a requirement as it is a boil and not anything that needs to be surgically removed. Unfortunately about 50% of patients who get anal abscesses may tend to develop fistula in a similar area. Fistulas, however, will require surgery.
