Post-Surgery Symptoms: Itching and Pain After Anal Fistula Repair - Surgery

Regarding anal abscess surgery?


Dear Doctor: I had surgery for an anal abscess (fistula surgery) last year, and the wound has healed, but there is a small scar left.
Occasionally, I feel itching around the anus.
I have gotten used to washing the anal area with clean water after bowel movements, but I am unsure if I am washing too vigorously or what, as sometimes I feel a slight stinging sensation when cleaning the anal area.
Additionally, when I touch the scar near the anus, I experience a brief stinging pain that quickly subsides.
I would like to know if this is related to the new tissue growth around the anus or if it is a normal phenomenon caused by the scar.
Can this improve? I have been feeling discomfort in that area throughout the day, and it has been about three months since my last surgery.

After surgery for an anal abscess, the wound is considered healed as long as there is no swelling, pain, or discharge.
Cleaning the anal area is a good hygiene practice, but it should be done gently since the skin around the anus is relatively delicate.
Vigorous cleaning may cause skin damage, which could lead to pain.
Additionally, it is not uncommon to experience a stinging sensation as scar tissue heals.
It is advisable to have a physician evaluate the area for any concerns.

More Info


After undergoing anal fistula repair surgery, it is not uncommon to experience a variety of sensations, including itching, pain, and discomfort around the surgical site. These symptoms can be attributed to several factors, including the healing process, scar tissue formation, and sensitivity of the newly formed tissue.

Firstly, it is important to understand that the healing of soft tissues, especially in sensitive areas like the anal region, can take time. The body goes through several stages of healing, which typically includes inflammation, tissue formation, and remodeling. During the initial healing phase, it is normal to experience some itching as the nerves regenerate and the skin begins to heal. This itching can be a sign of healing, but it can also be exacerbated by irritation from cleaning or wiping too vigorously.

The sensation of pain or a "stinging" feeling when cleaning the area may be due to several reasons. If you are washing the area too forcefully, it can irritate the sensitive skin and the underlying tissues, leading to discomfort. Additionally, the presence of scar tissue can also contribute to these sensations. Scar tissue is often less flexible and can be more sensitive than normal tissue, which may explain the "stinging" sensation when you touch the scar or the surrounding area.

It is also worth noting that the anal region is rich in nerve endings, and any surgical intervention can lead to heightened sensitivity during the healing process. As the new tissue forms, it may be more reactive to touch and pressure, which could explain the discomfort you are experiencing.

To manage these symptoms, consider the following recommendations:
1. Gentle Cleaning: When cleaning the area after bowel movements, use lukewarm water and avoid harsh soaps or vigorous scrubbing. Pat the area dry with a soft towel instead of rubbing it.

2. Moisturizing: Applying a gentle, fragrance-free moisturizer or a barrier cream around the area may help reduce itching and irritation. However, avoid applying anything directly into the anal canal unless advised by your healthcare provider.

3. Avoid Irritants: Be mindful of any products that may irritate the area, such as scented toilet paper or wipes. Opt for unscented and hypoallergenic options.

4. Pain Management: Over-the-counter pain relief medications, such as acetaminophen or ibuprofen, may help alleviate discomfort. However, consult with your healthcare provider before taking any medication.

5. Follow-Up Care: It is crucial to keep your healthcare provider informed about your symptoms. If the itching, pain, or discomfort persists or worsens, a follow-up appointment may be necessary to rule out any complications, such as infection or improper healing.

6. Physical Therapy: In some cases, pelvic floor physical therapy may be beneficial in addressing discomfort and improving the overall function of the anal region.

In conclusion, while some discomfort and itching after anal fistula repair surgery can be normal, it is essential to monitor your symptoms closely. If you have concerns about the nature of your symptoms or if they significantly impact your quality of life, do not hesitate to reach out to your healthcare provider for further evaluation and guidance. Healing can take time, and with appropriate care, many patients find that their symptoms gradually improve.
