An anorectal abscess

The sentences below are from two public pages opened October 27, 2026. They describe a pocket of pus. They do not identify one from a photograph or a symptom list. ahem has not examined anyone.

MedlinePlus reviewed this page on April 11, 2026. It calls an anorectal abscess a collection of pus in the area of the anus and rectum. Other names on the page are anal abscess, rectal abscess, perirectal abscess, perianal abscess, and gland abscess. Common causes it lists are blocked glands, infection of an anal fissure, a sexually transmitted infection, and trauma. Deep abscesses may come from intestinal disorders such as Crohn disease or diverticulitis.

Cleveland Clinic last updated its page on June 17, 2022. The heading is perianal abscess. The opening lines also say perineal abscess. Both point at a boil-like, pus-filled lump near the anus, rectum, or the space between the genitals and the anus, from a clogged, infected anal gland. The page says perianal abscesses are also called anal abscesses or anorectal abscesses.

MedlinePlus says common symptoms are swelling around the anus and a constant, throbbing pain. Pain may be severe with bowel movements, coughing, and sitting. Other symptoms it lists are constipation, discharge of pus, fatigue, fever, night sweats, chills, redness, hardened tender tissue, and tenderness. In infants, it says the abscess often appears as a swollen, red, tender lump at the edge of the anus, the infant may be fussy, and there are usually no other symptoms. That infant description is MedlinePlus only.

Cleveland Clinic's most common symptom, on the page checked October 27, 2026, is a swollen, tender boil near the edge of the anus. It may be red, extremely painful, or constantly throbbing. Sitting, coughing, and a bowel movement may hurt more. The longer list adds pus-like discharge, pain in the anus or rectum, a red swollen painful lump, constipation or painful bowel movements, irritation, rectal bleeding, and lower abdominal pain. Fever, chills, and other flu-like symptoms can occur. It says abscesses are most common in men and more likely between the ages of 20 and 60.

• Both pages: a painful, swollen area at the anus, worse with sitting or a bowel movement, and pus.
• Both pages: fever can be part of it.
• Cleveland Clinic adds rectal bleeding to the abscess symptom list. MedlinePlus puts bleeding on the list of reasons to contact a clinician, in the section below.

MedlinePlus says the problem rarely goes away on its own. Antibiotics alone usually cannot treat an abscess. Treatment involves surgery to open and drain it. The page says this is usually done with local numbing medicine and medicine to make the person sleepy, sometimes with spinal or general anesthesia, and usually as an outpatient. The surgeon cuts the abscess open and drains the pus. Sometimes a drain is left in, and sometimes the cavity is packed with gauze. Stitches are usually not needed. If the collection is deep, a longer hospital stay may be needed. After surgery, the page says warm sitz baths, sitting in a tub of warm water, may be needed to relieve pain and reduce swelling. It does not give a minute count or a water temperature. Stool softeners, fluids, and fiber are there to help avoid constipation.

Cleveland Clinic also says treatment is a clinician opening and draining the pus, and says not to attempt that at home. Drainage can be in the office with a numbing agent, or in a hospital with general anesthesia if the abscess is large or deep. A catheter is sometimes left in. Stitches are usually not needed. After that drainage, the page recommends a warm sitz bath several times a day, again with no minute count, plus antibiotics in some cases, stool softeners or laxatives, and pain medicine.

The split is the home-care paragraph on Cleveland Clinic's page. It says some perianal abscesses can be treated at home with warm compresses and sitz baths, that a clinician should be seen first, and that some clinicians may allow an abscess to drain on its own. If it breaks open on its own, the page says infection can spread. If one bursts, it says to wash with soap and water, cover it with a bandage, and watch it for several days. MedlinePlus does not describe home compresses or permission to wait. A reader cannot average those two pages into one instruction. The shared line is that popping it is not a home project, and a clinician decides whether to drain it.

Cleveland Clinic, on the page checked October 27, 2026, says a drained abscess takes three or four weeks to heal completely. It also says that, according to the American Society of Colon and Rectal Surgeons, about half of people who have an anal abscess will develop an anal fistula, which it defines as an infected tunnel between the skin and the anus. MedlinePlus does not print the three-or-four-week figure or the half. It does list an anal fistula as a complication, along with infection that spreads to the blood, continuing pain, and a recurring abscess.

Cleveland Clinic's complication list is an anal fistula, a recurring abscess, infection or sepsis, and Fournier's gangrene, which it calls a serious bacterial infection of the perineum. Its comparison with a hemorrhoid says hemorrhoids are swollen veins and are not an infection, and that an abscess tends to be more painful. Firmness is not a test a person can finish at home. The vein and the clot are on complications the sources name. The tunnel is on an anal fissure and an anal fistula, and the operations are on surgery for an anal fistula.
