It could possibly be a diverticulum.
It would be best for a physician to examine it in person for a more accurate diagnosis.
If it is confirmed to be a diverticulum, surgical removal should be performed as soon as possible.
If left untreated for a long time, it may develop into a complicated diverticulum, which would make management more difficult.

More Info

Anal fistulas are abnormal connections that develop between the anal canal and the skin surrounding the anus. They often arise as a complication of anal abscesses, which are collections of pus that can occur due to infections in the anal glands. Understanding the symptoms, risks, and treatment options for anal fistulas is crucial for effective management and prevention of complications.

Symptoms of Anal Fistulas
The symptoms of an anal fistula can vary, but common signs include:
1. Swelling and Tenderness: There may be a noticeable lump or swelling near the anus, which can be tender to the touch.

2. Discharge: Fistulas often produce a discharge that may be pus-like or bloody, which can irritate the surrounding skin.

3. Pain: While some fistulas may not cause pain, others can lead to discomfort, especially during bowel movements.

4. Itching or Irritation: The area around the fistula may become itchy or irritated due to the discharge.

5. Recurrent Abscesses: Individuals with anal fistulas may experience recurrent anal abscesses, which can lead to further complications.

Risks of Untreated Anal Fistulas
If left untreated, anal fistulas can lead to several complications:
1. Infection: The risk of recurrent infections increases, leading to more abscesses and potential systemic infections.

2. Chronic Discomfort: Persistent symptoms such as discharge and irritation can significantly affect quality of life.

3. Fistula Recurrence: Untreated fistulas may not heal properly and can recur, leading to the need for more extensive surgical intervention later.

4. Incontinence: In rare cases, if the fistula is extensive or improperly treated, it can lead to fecal incontinence due to damage to the anal sphincter muscles.

Treatment Options
Treatment for anal fistulas typically involves surgical intervention, as conservative measures are often ineffective. The main treatment options include:
1. Fistulotomy: This is the most common surgical procedure for anal fistulas. It involves cutting open the fistula tract to allow it to heal from the inside out. This procedure is usually effective but may require careful management to avoid damage to the anal sphincter.

2. Seton Placement: In cases where the fistula is complex or involves significant sphincter muscle, a seton (a piece of surgical thread) may be placed to help drain the fistula and promote healing over time. This method allows for gradual division of the fistula without risking incontinence.

3. Flap Procedures: For more complicated fistulas, flap procedures may be used to cover the internal opening of the fistula with healthy tissue, promoting healing while preserving sphincter function.

4. Fibrin Glue or Bioprosthetic Plug: These are less common options that involve sealing the fistula tract with a special glue or plug, although they may have higher rates of recurrence compared to surgical options.

Conclusion
If you notice a lump near your anus that is not painful, itchy, or bleeding, it could potentially be an anal fistula or another condition. It is essential to consult a healthcare professional for an accurate diagnosis and appropriate management. Early intervention can prevent complications and improve outcomes. Regular follow-ups and adherence to treatment plans are crucial for managing anal fistulas effectively. If you have any concerns about your symptoms or treatment options, do not hesitate to reach out to a healthcare provider for guidance.
