Anal perianal skin fissure?


Hello doctor, I recently experienced a rupture in the skin around my anus.
Previously, this only happened around my menstrual period due to chafing from sanitary pads, but this time it occurred without any such reason, and it has split along the anal cleft.
I initially thought it would heal on its own, but the pain has increased.
A classmate lent me some topical medication, which seemed to help at first, but today it feels worse again.
Additionally, I suspect I might have a yeast infection in my vulva; I wonder if this is related.
What should I do about the situation?

More Info


Anal skin fissures, also known as anal fissures, are small tears in the skin around the anus. They can be quite painful and are often associated with symptoms such as sharp pain during bowel movements, bleeding, and discomfort in the anal area. Understanding the causes, symptoms, and treatments for anal skin fissures is essential for effective management and relief.


Causes of Anal Skin Fissures
1. Trauma or Injury: The most common cause of anal fissures is trauma to the anal canal, often due to passing hard or large stools. This can occur in individuals who experience constipation or straining during bowel movements.

2. Chronic Diarrhea: Frequent bowel movements can also lead to irritation and tearing of the anal skin, resulting in fissures.

3. Inflammatory Conditions: Conditions such as Crohn's disease or ulcerative colitis can cause inflammation in the gastrointestinal tract, leading to fissures.

4. Infections: Fungal infections, such as a yeast infection (which you mentioned), can irritate the skin and contribute to the development of fissures.

5. Skin Conditions: Certain skin conditions, like psoriasis or eczema, can affect the anal area and lead to fissures.

6. Poor Hygiene: Inadequate cleaning after bowel movements can lead to irritation and increase the risk of fissures.


Symptoms of Anal Skin Fissures
- Pain: The most prominent symptom is sharp pain during and after bowel movements. This pain can be severe and may last for several hours.

- Bleeding: You may notice bright red blood on the toilet paper or in the stool.

- Itching or Irritation: The area may feel itchy or irritated, especially if there is an associated infection.

- Visible Tear: A fissure may be visible as a small tear or crack in the skin around the anus.


Treatment Options
1. Dietary Changes: Increasing fiber intake can help soften stools and reduce straining during bowel movements. Drinking plenty of water is also essential.

2. Topical Treatments: Over-the-counter creams or ointments containing hydrocortisone can help reduce inflammation and pain. Additionally, topical anesthetics may provide temporary relief.

3. Sitz Baths: Soaking the anal area in warm water for 10-15 minutes several times a day can help soothe discomfort and promote healing.

4. Medications: In some cases, a doctor may prescribe medications to help relax the anal sphincter, which can reduce pain and promote healing.

5. Avoiding Irritants: If you suspect that a yeast infection or other irritant is contributing to your symptoms, addressing that condition is crucial. Antifungal creams or medications may be necessary for a yeast infection.

6. Surgery: In chronic cases where conservative treatments fail, surgical options such as lateral internal sphincterotomy may be considered to relieve tension in the anal sphincter and promote healing.


When to Seek Medical Attention
If your symptoms persist or worsen despite home treatment, or if you notice significant bleeding, it is essential to consult a healthcare provider. They can perform a thorough examination, rule out other conditions, and recommend appropriate treatments tailored to your specific situation.

In your case, since you mentioned experiencing a yeast infection, it is crucial to address that issue as it may be contributing to the irritation and pain around the anal area. Additionally, maintaining good hygiene and avoiding irritants will help in managing and preventing further fissures.

In summary, anal skin fissures can be painful and disruptive, but with proper care and treatment, they can heal effectively. If you have any concerns or if your symptoms do not improve, do not hesitate to reach out to a healthcare professional for further evaluation and management.
