What is the redness around the anus

Although the anus performs the dirtiest job in the body, it is actually very important. However, in daily life, many people have abnormal conditions in their anus, such as redness around the anus, which is a typical example. Although there are no obvious symptoms, patients are still very worried and afraid that there will be major impacts. So, what is the cause of redness around the anus? Let’s take a closer look below.

This is a typical perianal abscess, which is a common anorectal disease. It is an acute suppurative infection in the soft tissue around the anal canal and rectum or in the surrounding spaces, resulting in the formation of an abscess. The main symptoms of perianal abscess are redness, swelling, severe pain or throbbing pain around the anus, a heavy and swollen anus, painful lumps that can be felt around the anus, and even difficulty in urination and defecation. The formation of perianal abscess occurs three to seven days after the onset of the disease. After the perianal abscess ruptures, the pain and systemic symptoms are relieved, and anal fistula is subsequently formed.

1. Perianal subcutaneous abscess: The main symptom is pain, which is initially distending pain, throbbing pain when purulent, and pain aggravated by defecation. Urinary retention may occur when the abscess is in front of the anus, and pain in the coccyx may occur when the abscess is behind the anus. Symptoms of systemic poisoning are mild, with local swelling, redness, tenderness, and fluctuation.

2. Ischiorectal fossa abscess: The patient has symptoms of systemic poisoning such as general discomfort, fever, chills, and increased body temperature. Local symptoms include swelling, redness, burning pain, throbbing pain, tenderness, restlessness on one side of the anus; the pain worsens during activity and defecation; and urination is difficult.

3. Pelvic rectal abscess: The patient has severe systemic symptoms, first with chills, high fever, and general fatigue. In severe cases, there may be symptoms of sepsis poisoning. The local symptoms are mild, with only a feeling of rectal prolapse, soreness or discomfort, and difficulty urinating may also occur.

4. Retrorectal abscess: The systemic symptoms are similar to those of pelvic rectal fossa abscess, but the local symptoms are mainly soreness, swelling and heaviness in the coccyx and lumbar region, radiating to the back and thighs on both sides. There is tenderness in the coccyx and the patient cannot sit upright.

5. Rectal submucosal abscess: The patient feels general discomfort, fatigue and fever. The main local symptom is rectal irritation, including tenesmus, heaviness in the abdomen, frequent bowel movements or a feeling of urge to defecate. Tuberculous anorectal abscess is different from the above-mentioned bacterial infection. Patients often have a chronic disease, and the abscess will take weeks or months to form. The local pain is not severe, accompanied by low fever, and the local redness and swelling are not obvious. The pus flowing out after rupture is clear and milky white. The pus opening is sunken, and the surrounding skin is blue or bluish-white. There are often multiple external openings for pus to flow, and it does not heal for a long time. A systemic examination can reveal tuberculosis lesions in the lungs, large intestine, or other parts of the body, and pus culture can find Mycobacterium tuberculosis.

The above is an introduction to what causes redness around the anus. I hope it will be helpful to everyone’s understanding. Redness around the anus is likely a sign of perianal abscess. You can compare these symptoms with your own symptoms. If the similarity is high, it is recommended that you go to a regular hospital for comprehensive diagnosis and treatment in time, and take daily care measures to recover as soon as possible.
