Q: Burning Sensation Around Anus After Bowel Movement: Causes and Solutions

After having a bowel movement and cleaning thoroughly, there is a burning sensation around the anal area?

Hello Doctor, I underwent anal fistula excision surgery at the end of last year.
Postoperatively, my wound healing was not very good due to excessive granulation tissue formation, so I received cryotherapy at a dermatology clinic along with antibiotic and steroid ointment applications.
Currently, the wound has healed into a fibrous scar.

I would like to ask you about a month after starting cryotherapy, I began to experience a stinging and burning sensation in the skin near the anal folds on the opposite side of the wound (where there were no lesions).
I am unsure if this was caused by the clinic's physician accidentally spraying the cryotherapy agent onto the normal skin on the other side.
The burning sensation only occurs after I wash my buttocks following a bowel movement (it does not occur before having a bowel movement).

I have also visited a colorectal specialist who examined the wound and informed me that there were no issues with the original surgical site, suggesting that the burning sensation might be a side effect of the medication I applied earlier.

Could you please advise if this situation is due to skin damage from the cryotherapy or the ointment application? Or could there be another cause? What can I do to improve this condition? (I have not used the steroid ointment for 25 days and I rinse with water after using the restroom.) Thank you for your assistance!

Hello: Based on the description, if the cryogenic spray has come into contact with the normal skin on the other side, the burning and stinging sensation is likely to be most pronounced in the first few days following the cryotherapy.
The burning pain around the anal area can have many causes, such as hard stools causing friction during passage, excessive force from water washing, prolonged moisture leading to skin inflammation, fungal infections, etc.
If the skin symptoms do not improve or worsen, it is advisable to consult a dermatologist for diagnosis and treatment.
Thank you!

More Info

The burning sensation around the anus after bowel movements can be a distressing symptom, especially following a surgical procedure like anal fistula excision. Based on your description, it seems that you have undergone a significant surgical intervention and subsequent treatments, including cryotherapy and the application of topical medications.
Firstly, the burning sensation you are experiencing could be attributed to several factors. One possibility is that the cryotherapy treatment may have inadvertently affected the surrounding skin, leading to irritation or damage. Cryotherapy works by freezing abnormal tissue, but if the spray inadvertently contacted normal skin, it could cause localized inflammation or a burn-like sensation.
Another potential cause for the burning sensation could be related to the healing process of the surgical site. After surgery, the area around the anus can be sensitive, and any form of irritation, whether from bowel movements, hygiene practices, or even the application of topical medications, can exacerbate discomfort. The fact that you only experience this sensation after bowel movements suggests that the act of passing stool or cleaning the area may be triggering the discomfort.
Additionally, the use of topical steroids, while beneficial for reducing inflammation, can sometimes lead to skin thinning or irritation, especially with prolonged use. If you have recently stopped using the steroid ointment, it is possible that your skin is adjusting, which could also contribute to the burning sensation.

To address your concerns, here are some recommendations:
1. Gentle Hygiene Practices: After bowel movements, consider using a gentle, non-irritating cleanser and avoid scrubbing the area. Patting the area dry with a soft towel can also help minimize irritation.

2. Warm Sitz Baths: Taking warm sitz baths can provide relief by soothing the area and promoting blood flow, which can aid in healing.

3. Avoid Irritants: Be cautious with any products you apply to the area, including soaps, wipes, or creams. Opt for fragrance-free and hypoallergenic options to reduce the risk of irritation.

4. Monitor Symptoms: Keep track of when the burning sensation occurs and any associated activities. If it worsens or does not improve, it may be worth revisiting your healthcare provider for further evaluation.

5. Consultation with Specialists: If the burning sensation persists, consider consulting a colorectal specialist. They can perform a thorough examination to rule out any underlying issues, such as skin irritation, infection, or other complications related to your previous surgery.

6. Dietary Considerations: Sometimes, dietary factors can contribute to anal discomfort. Ensure you are consuming a fiber-rich diet to promote soft stools and reduce straining during bowel movements.

In conclusion, while the burning sensation you are experiencing could be related to the cryotherapy or the healing process post-surgery, it is essential to monitor your symptoms closely. If the discomfort continues or worsens, seeking further medical advice is crucial to ensure proper management and to rule out any complications. Your comfort and health are paramount, and addressing these symptoms early can lead to better outcomes.
