Perianal itching and burning?


Hello, doctor.
I've been struggling with perianal itching for about two weeks.
Initially, I thought it was due to exam stress leading to increased hygiene habits, so I started using a bidet and reduced the frequency of wiping and washing.
However, this only improved the discomfort of the anus itself.
The skin just outside the anal opening still occasionally itches and even stings, especially when sitting or walking for extended periods (standing still does not cause any sensation).
I asked a family member to check, and there is no redness or wounds in the surrounding area.
I would like to ask the following questions:
1.
Could the itching of the skin just outside the anal opening be due to winter dryness or excessive hair around the anus? Sometimes, I even experience similar sensations in the perineal area.

2.
If it is indeed due to dryness or long anal hair, is it safe to apply petroleum jelly?
3.
Sometimes, after having a bowel movement in the morning and cleaning thoroughly, I find that by the evening, after showering and drying with toilet paper, there is still fecal matter around the anal opening.
Could passing gas cause this phenomenon?

1.
Winter is a common season for anal itching, similar to the occurrence of dry skin.
2.
It is possible.
3.
There may always be a small amount of fecal matter or secretions around the anal area, which can cause irritation or result from low anal pressure.
Anal itching may also be caused by excessive wiping.
There are three important points to pay special attention to: 1.
Do not scratch to avoid causing a wound infection.
2.
Temporarily avoid consuming spicy foods to prevent capsaicin from irritating the skin.
3.
Avoid using soap or body wash to clean the anal area to prevent excessive removal of the skin's natural oils.
If these points are followed, improvement can generally be seen in about a week.
If there is no improvement, it is advisable to consult a physician for evaluation and possible medication.

More Info


Anal itching and discomfort can be a frustrating and embarrassing issue, but it is important to understand that it is a common problem that can arise from various causes. Based on your description, it seems that you have been experiencing discomfort around the anal area for about two weeks, which has not improved significantly despite your efforts to reduce irritation through less frequent cleaning. Let's address your questions one by one and provide some insights into potential causes and solutions.

1. Causes of Itching in the Skin Outside the Anus: The itching you are experiencing in the skin just outside the anus could indeed be related to dryness, especially during the winter months when the air tends to be drier. Dry skin can lead to irritation and itching, particularly in sensitive areas. Additionally, if you have been cleaning the area excessively, it may have led to a disruption of the natural skin barrier, making the skin more susceptible to irritation. Another potential cause could be related to hair in the anal region. If the hair is too long, it can trap moisture and bacteria, leading to irritation and discomfort. It is also worth noting that certain skin conditions, such as eczema or psoriasis, can cause similar symptoms.

2. Using Vaseline for Dryness: Applying a barrier cream like Vaseline (petroleum jelly) can be beneficial if dryness is a contributing factor to your discomfort. It can help to lock in moisture and protect the skin from further irritation. However, it is essential to apply it sparingly and ensure that the area is clean before application to avoid trapping bacteria or fecal matter, which could exacerbate the issue.

3. Post-Bowel Movement Discomfort: It is not uncommon for some residual fecal matter to remain after wiping, especially if the stool is soft or if there is a tendency for the skin to be moist. This can lead to irritation and itching later in the day. Additionally, passing gas can sometimes cause a small amount of stool to be expelled, which could contribute to the sensation of needing to clean again. To mitigate this, consider using moist wipes designed for sensitive skin after bowel movements, as they can help ensure the area is thoroughly cleaned without excessive friction.

In summary, the discomfort you are experiencing could be attributed to a combination of dryness, excessive cleaning, and possibly hair in the anal region. Here are some recommendations to help alleviate your symptoms:
- Limit Cleaning: While it is essential to keep the area clean, excessive washing can lead to irritation. Try to find a balance that keeps the area clean without overdoing it.

- Moisturize: Use a gentle, fragrance-free moisturizer or barrier cream like Vaseline to help with dryness.

- Grooming: If you feel comfortable, consider trimming the hair in the anal region to reduce moisture retention and irritation.

- Gentle Wipes: Use moist wipes after bowel movements to ensure cleanliness without causing irritation from excessive wiping.

- Consult a Healthcare Provider: If your symptoms persist or worsen, it is advisable to consult a healthcare provider. They can assess for any underlying conditions, such as infections or skin disorders, and provide appropriate treatment options.

Remember, while anal itching can be uncomfortable, it is often manageable with the right care and attention. If you have any concerns about your symptoms or if they do not improve, seeking professional medical advice is always a good step.
