Anal Infections: Causes, Treatments, and Concerns

Anal infection!? Anal abscess!?

Hello Doctor: Initially, I had a problem with hemorrhoids, and I experienced blood drops during bowel movements.
After visiting the hospital, the doctor prescribed me hemostatic medication and suppositories for treatment.
Since I have Myelodysplastic Syndromes (MDS), my blood-related capabilities are not very good, so I also bought an ointment from the pharmacy to apply (I used my finger to apply the ointment inside the anal cavity, and I'm not sure if that caused an infection...).
Recently, I noticed a swollen bump near my anus that resembles an acne lesion, which is painful when pressed.
The doctor at the hospital told me it was an anal infection and prescribed a week’s worth of antibiotics.
After taking them for a week, the swollen bump next to my anus has disappeared and is no longer painful.
I have researched some information, but I still have some concerns! I would like to ask you, Doctor...
1.
Since the outpatient doctor only prescribed me a week’s worth of antibiotics and did not provide any other treatment, even though the swollen bump has disappeared, will it reoccur after stopping the medication? 2.
Later, I caught a cold with a cough and throat inflammation, and the ENT doctor prescribed me more antibiotics.
Combined with the hemorrhoid medication, I have been taking antibiotics for almost two weeks.
I would like to know if taking antibiotics for such a long time could worsen the inflammation of the anus?

If it is a mild anal infection, a week of antibiotic treatment is indeed sufficient.
If symptoms do not improve, incision and drainage surgery may be necessary.
Since the swelling and lumps around the anus have disappeared and there is no pain, it indicates that the anal inflammation has improved, so there is no basis for saying it has worsened.
The notion that excessive antibiotic use leads to the spread of fistulas is also incorrect; it is the recurrent inflammation that causes the fistula to spread, which is also the reason for the continuous need for antibiotics.

More Info

Understanding anal infections, particularly in the context of your situation, involves recognizing the causes, potential treatments, and the concerns that arise from using medications like antibiotics, especially when you have underlying health conditions such as myelodysplastic syndromes (MDS).

1. Causes of Anal Infections: Anal infections can arise from various factors, including poor hygiene, skin irritations, or the introduction of bacteria through the use of topical medications. In your case, the application of ointment inside the anal canal could have introduced bacteria, especially if the area was not clean or if the ointment was contaminated. Conditions like hemorrhoids can also lead to inflammation and secondary infections due to the irritation and trauma they cause during bowel movements.

2. Treatment and Concerns: The treatment for anal infections typically involves antibiotics to combat bacterial infections. The fact that your swelling and pain resolved after a week of antibiotic treatment is a positive sign. However, your concern about the recurrence of the swelling after stopping the antibiotics is valid. While antibiotics can effectively eliminate the infection, they do not address the underlying causes, such as hemorrhoids or hygiene issues. If the original cause persists, there is a possibility that the infection could recur. It would be prudent to follow up with your healthcare provider if you notice any returning symptoms.

3. Impact of Prolonged Antibiotic Use: Taking antibiotics for an extended period, as you have done, can lead to several concerns. One of the most significant risks is the development of antibiotic resistance, which can make future infections harder to treat. Additionally, prolonged use of antibiotics can disrupt the normal flora of the gut, potentially leading to conditions like Clostridium difficile infection, which can cause severe diarrhea and colitis. However, in your case, if the antibiotics were prescribed for legitimate infections, the benefits may outweigh the risks, provided they are monitored by your healthcare provider.

4. Monitoring and Prevention: After completing your antibiotic course, it is essential to monitor for any signs of recurrence, such as pain, swelling, or discharge. Maintaining good hygiene, avoiding irritants, and managing any underlying conditions like hemorrhoids can help prevent future infections. If you experience recurrent issues, it may be beneficial to consult a specialist, such as a gastroenterologist or a colorectal surgeon, who can provide more targeted treatment options.

5. Consultation with Healthcare Providers: Given your history of MDS and the potential complications associated with it, it is crucial to communicate openly with your healthcare providers about any new symptoms or concerns. They can help tailor your treatment plan, considering your overall health and any medications you are taking.

In summary, while your initial treatment appears to have been effective, ongoing vigilance is necessary to prevent recurrence. If you have further concerns about the effects of prolonged antibiotic use or the management of your anal health, do not hesitate to reach out to your healthcare provider for personalized advice and support.
