What symptoms occur with an anal abscess?
The symptoms of an anal abscess can be very unpleasant and painful for those affected. The classic symptoms of an anal abscess are local pressure and increasing persistent pain when sitting or during bowel movements. Other symptoms of an anal abscess include local redness around the anus, as well as hardening and warmth in the anal region. Burning sensation at the anus can also occur with anal abscesses. In larger or deeper tissue abscesses, symptoms can become more nonspecific and may include fever, chills, fatigue, or general malaise. If these symptoms occur, prompt medical examination is necessary, as medical treatment of the abscess is generally required. Pus discharge in the anal area can also occur if the abscess bursts on its own or if an anal fistula has already formed due to chronic inflammation or the anal abscess. Occasionally, an abscess breaks open and the pus drains. When the anal abscess opens and pus escapes, the pressure pain in the anal area may subside, but this often leads to severe anal itching and skin irritation in the anal area.
What are the first signs of an anal abscess?
The first signs of an anal abscess are usually due to inflammation in the anal area and can appear relatively suddenly. Typical initial symptoms or signs of an anal abscess include the following complaints:
Severe pain in the anal area or pressure pain, which can often be pulsating and worsens when sitting or during bowel movements.
Redness and swelling around the anus. A small, hard or soft swelling near the anus may be felt or visible. The swelling is usually also tender to pressure. The skin around the affected area may be red, indicating local inflammation at the anus.
Pressure or tension sensation and warmth
Some affected individuals describe an unpleasant pressure sensation in the anal area that worsens over time.
Fever, a general feeling of illness or deterioration of overall condition, especially with larger or deeper anal abscesses.
Problems with bowel movements can result mainly due to the increasingly severe pain at the anus.
Also, burning at the anus can occur with anal abscesses. The inflammation and pressure of the pus on the surrounding tissue can cause a burning sensation. This feeling can be especially intensified after bowel movements due to increased irritation of the affected tissue. Read more about burning at the anus here.
These first signs of an anal abscess often worsen rapidly, which is why early medical evaluation of the symptoms of an acute anal abscess is strongly recommended to prevent further complications such as chronicity in the progressing disease course or even the occurrence of an anal fistula.
How do the symptoms of the different types of anal abscesses differ?
Anal abscesses can manifest differently depending on their exact location in the body. Thus, symptoms can vary greatly depending on the type of abscess.
The perianal abscess, which forms directly under the skin around the anus, is characterized by a clearly visible swelling and redness accompanied by severe, pressing pain. These pains typically worsen when sitting or during bowel movements, and sometimes pus can discharge if the abscess bursts spontaneously.
In contrast, the intersphincteric abscess lies between the internal and external sphincter muscles, causing deeper and more intense pain at the anus. Externally, fewer visible signs such as swelling are noticeable, but affected individuals experience significant discomfort during bowel movements, and fever may occur.
The ischiorectal abscess, which lies deeper in the fat tissue next to the anal canal, causes severe, deep-seated pain that often radiates into the surrounding buttocks. In this case, a hard swelling in the buttock area is also palpable, accompanied by general symptoms such as fever and fatigue.
In supralevator abscesses, which are located above the levator ani muscle in the pelvic area, the pain is often deeper and radiates to the lower back or lower abdomen. There are no externally visible swellings, but affected individuals suffer from high fever and a general feeling of illness.
Finally, there is the submucosal abscess, which is located directly under the mucous membrane of the anal canal and is characterized by severe pain during bowel movements. This abscess is hardly visible externally, but pus can be detected during a rectal examination.
All these anal abscesses share the feature of causing severe pain in the anal area, accompanied by a feeling of pressure and warmth in the affected tissue. Without treatment of the abscess, these can progress and lead to fistula formation, which is a chronic complication of the disease course. Read more here about the anal abscess surgery.
When to see a doctor for symptoms of an anal abscess?
The symptoms of anal abscesses require medical evaluation. As soon as symptoms of an anal abscess or initial signs appear, you should consult your general practitioner or a proctology specialist. They will first assess the complaints, medical history, and perform a physical examination of the patient. The diagnosis of an anal abscess is thus based on a careful medical evaluation of the symptoms as well as a thorough, further physical examination by medical professionals. To determine the type and extent of the anal abscess, the doctor first takes the medical history. An external examination of the anal area gives the doctor a first impression of the severity and course of the disease. Furthermore, a palpation examination is performed. If the anal abscess is located in the inner part of the anal area, an endoscopic examination for more precise localization of the abscess can provide a better overview of the severity of the abscess. The depth extension of an anal abscess is examined by ultrasound.
How can I relieve the symptoms of an anal abscess?
Relieving the symptoms of an anal abscess mainly focuses on reducing pain at the anus and supporting the healing of the affected tissue. It is important to emphasize here that medical treatment of the abscess is absolutely recommended. Usually, the abscess must be surgically drained. However, you can alleviate the symptoms or even accelerate tissue healing after an anal abscess operation with some measures.
Sitz baths
Sitz baths, several times a day, can relieve pain at the anus and promote blood circulation in the affected anal area. Improved blood circulation can help accelerate the healing of the affected tissue. Use warm water, to which you can also add a little chamomile or antiseptic additives.
Painkillers and antibiotics
Ibuprofen or paracetamol as non-steroidal anti-inflammatory drugs (NSAIDs) can help relieve pain and inflammation. These medications can also help reduce mild fever that may occur with an abscess. In some cases, a doctor may prescribe antibiotics before surgical drainage to contain the infection, especially if there is a risk of spreading the infection.
Avoiding pressure on the anal area and promoting soft bowel movements
Sitting cushions or avoiding prolonged sitting can reduce pressure on the anal area and thus reduce pain. A fiber-rich diet (e.g., fruits, vegetables, whole grains) and plenty of fluids help keep stools soft. Laxatives or stool softeners can also be helpful to reduce pressure during bowel movements and relieve pain.
Anal hygiene
Thorough hygiene in the anal area is crucial to prevent further infection. Gently cleaning the affected area after bowel movements, preferably with water, can minimize irritation.
Avoiding irritants
Avoid wearing tight or chafing clothing to prevent additional irritation of the affected area. Natural underwear is best suited to keep the intimate or anal area breathable and dry.
Despite these measures, an anal abscess can only be fully treated by surgical drainage. The steps mentioned here only relieve symptoms and do not constitute medical treatment of the anal abscess. If symptoms such as severe pain, swelling, or fever occur, a doctor should be consulted immediately to avoid further complications such as uncontrolled abscess drainage or even chronicity leading to an anal fistula.
How quickly do symptoms of anal abscesses subside after surgery?
Anal abscesses are usually treated surgically. By relieving pressure and allowing pus to drain, symptoms and complaints usually improve very quickly. Often, the anal abscess surgery is performed under general or local anesthesia on an outpatient basis. Occasionally, a wound drain must be inserted, which may remain in the wound for some time. To prevent a new abscess from forming, the wound is not closed. After the anal abscess operation, the wound at the anus should be kept as clean as possible. Additionally, the wound should be rinsed 1-2 times a day after surgery. Minor bleeding in the anal region is normal after a surgical procedure on inflamed tissue and should not be a cause for concern. Pain in the anal region is also normal after the anal abscess surgery. To relieve pain, painkillers can be taken or alternative treatments considered. If the abscess was located close to the anus, soft stools facilitate wound healing and can also accelerate the healing time. A few weeks after the anal abscess operation, a follow-up medical check-up is also performed to ensure there are no recurring abscesses or even anal fistulas or other proctological complications.
How do the symptoms differ between anal abscess and anal fistula?
The anal abscess is characterized symptomatically by its sudden, painful, and inflammatory nature, while the anal fistula tends to have a chronic, less intense course with persistent secretion discharge. An anal abscess and an anal fistula thus present with different symptoms, which are due to their respective inflammatory status and disease progression.
The anal abscess shows acute, severe pain at the anus, often pulsating and significantly worsening when sitting or under pressure. These pains in the anal area are also accompanied by visible swelling, redness, and warmth in the affected area around the anus. Fever and general malaise can also occur as systemic symptoms of the inflammation. Often, there is a sudden discharge of pus when the abscess spontaneously drains. Consequently, an anal fistula very frequently develops from an anal abscess if no timely treatment of the abscess is initiated. The abscess has a rather short-term course and is considered an acute inflammation.
In contrast, the anal fistula is the chronic stage of the disease, where pain at the anus is usually less intense but mainly persistent. The characteristic symptom of an anal fistula is a continuous discharge of pus, fluid, or secretion from the external fistula opening near the anus. This often leads to intense anal itching, irritation, and occasionally even bleeding in the anal area. Fever is rare with an anal fistula. The symptoms of an anal fistula develop more slowly and persist over a longer period, whereas the anal abscess usually presents with an acute, sudden onset of symptoms.
