Wound after drainage of an anal abscess?


Hello, Doctor.
I was diagnosed with an anal abscess on April 1st, and a blade was used for drainage at that time.
During my follow-up appointment on April 8th, the doctor examined the wound and confirmed that it was healing well, advising that I wouldn't need to return unless there was a recurrence.
However, the doctor mentioned that due to fibrosis at the incision site, there is a small hard lump that may gradually disappear or may not.
I haven't had any issues until May 15th when I gently pressed on the hard lump at the wound site and noticed a slight pain.
I would like to know if this situation is normal.

If the anal abscess has been adequately drained and there are no secretions or signs of redness, swelling, or pain, it can be considered as not having recurred.
The healing site may develop fibrotic scarring, but it typically does not cause significant discomfort.
If there are any concerns, a follow-up appointment can be made to examine the wound.

More Info


After undergoing drainage for an anal abscess, it is essential to understand the proper care for the wound to ensure optimal healing and to prevent complications. Based on your description, it seems that you have already received initial treatment and follow-up care, which is a good start. However, your concern about the hard lump and mild pain at the site of the incision is valid and warrants further discussion.

Firstly, it is not uncommon to experience some degree of hardness or lumpiness at the site of an incision after drainage of an abscess. This can be attributed to several factors, including scar tissue formation (fibrosis) and inflammation. The body’s natural healing process often leads to the formation of scar tissue, which may feel firm or hard to the touch. Over time, this tissue may soften and become less noticeable, but in some cases, it may persist.

The mild pain you are experiencing when pressing on the hard lump could be due to several reasons:
1. Healing Process: As the wound heals, the surrounding tissues may still be sensitive. Light pressure on the area can cause discomfort, especially if the tissues are still inflamed or if there is residual swelling.

2. Scar Tissue: The formation of scar tissue can lead to sensitivity in the area. This is particularly true if the scar tissue is still maturing. Scar tissue can sometimes be more sensitive than the surrounding skin, leading to pain when pressure is applied.

3. Infection: While you mentioned that there have been no signs of recurrence, it is crucial to monitor for any signs of infection, such as increased redness, warmth, swelling, or discharge from the wound. If you notice any of these symptoms, it would be advisable to seek medical attention promptly.

4. Abscess Recurrence: Although your doctor indicated that you do not need to return unless there is a recurrence, it is essential to remain vigilant. If you experience increased pain, swelling, or any other concerning symptoms, it is wise to consult your healthcare provider.

In terms of wound care, here are some general recommendations:
- Keep the Area Clean: Gently clean the area around the incision with mild soap and water. Avoid using harsh chemicals or scrubbing the area, as this can irritate the skin and delay healing.

- Monitor for Signs of Infection: As mentioned earlier, watch for any signs of infection. If you notice increased pain, redness, swelling, or discharge, contact your healthcare provider.

- Avoid Excessive Pressure: While it is natural to want to check the area, avoid applying excessive pressure to the hard lump. This can exacerbate discomfort and potentially disrupt the healing process.

- Follow-Up Care: If you have ongoing concerns about the hardness or pain at the site, consider scheduling a follow-up appointment with your healthcare provider. They can assess the area and determine if any further intervention is necessary.

- Pain Management: If the pain is bothersome, over-the-counter pain relievers such as acetaminophen or ibuprofen may help alleviate discomfort. However, consult your healthcare provider before starting any new medication.

In conclusion, while some hardness and mild pain at the site of an anal abscess drainage are not uncommon, it is essential to monitor the area for any changes. If you have concerns or if the symptoms worsen, do not hesitate to reach out to your healthcare provider for further evaluation and guidance. Proper wound care and monitoring are crucial for a smooth recovery.
