About this condition
Paraproctitis refers to infection and pus formation in tissues around the rectum; a perianal abscess is one possible presentation. Increasing pain, swelling and fever require prompt clinical assessment rather than routine self-treatment.
What you should know
The infection may begin when small anal glands become blocked. Pus can collect in deeper tissues without a clearly visible surface lump. Diabetes, impaired immunity and some bowel disorders may complicate the course. A spontaneous discharge of pus does not establish that the infection has resolved.
Symptoms and reasons for assessment
Typical signs include persistent or throbbing pain near the anus, a tender swelling, redness, warmth, fever and chills. Sitting or opening the bowels may worsen the pain. Some people develop a discharge, but deep abscesses may cause severe pain without obvious changes to the skin.
Other possible explanations
A thrombosed external haemorrhoid, inflamed cyst or superficial skin infection can resemble an abscess. Examination must establish whether a pus-filled cavity exists and how far the infection extends; treating every painful lump as haemorrhoids can delay needed care.
How the problem is assessed
A clinician assesses general condition, temperature, tenderness and the local area. Suspected deep collections may require imaging or an examination by a colorectal surgeon. Investigations depend on severity and should not delay care when acute infection is evident.
Treatment and follow-up options
A formed abscess often needs incision and drainage by a qualified specialist; antibiotics alone may not provide adequate drainage. After the acute episode, follow-up may be recommended because an anal fistula can develop. The precise procedure and where it is available are decided individually with the treating team.
When urgent care is needed
Rapidly increasing pain or swelling, fever, chills, marked weakness or deterioration requires urgent medical assessment, not a standard appointment. Do not squeeze or puncture the swelling at home. If the person is severely unwell or a life-threatening emergency is suspected, call 103.

Frequently asked questions
Can creams alone cure a perianal abscess?
Usually not. A formed collection of pus often requires specialist drainage; applying creams can postpone appropriate treatment.
Can an anal fistula form after an abscess?
Yes. In some people a channel persists between the anal canal and skin, causing recurring discharge.
What if the abscess bursts on its own?
Pain or pressure may improve temporarily, but a residual cavity or fistula is possible. Arrange medical assessment.
