Pimples on the anus are a sign of what disease?

Question
Hello doctor,
I was constipated for 3 days and then got a lump like flesh near the anus, red and swollen, very painful when walking. After two days, the pus broke with blood and mucus, and the acne healed without any more fluid but did not collapse. I went to the doctor and the doctor said it was an anal fistula but the ultrasound did not show the fistula. 2 days ago, the acne swelled up and burst pus with blood and mucus. So the doctor told me that acne on the anus is a sign of disease? Do you have an anal abscess or an anal fistula? Thank you doctor.

Hello,
With the question “What is an anal pimple a sign of disease? ”, the doctor would like to answer as follows:
According to your description, the doctor thinks a lot about anal abscess, however, the combined anal fistula has not been ruled out. You should see a doctor for an accurate diagnosis, MRI of the anorectal area will help make a clearer diagnosis. Anal abscess or anal fistula also require surgery, because the recurrence rate is high, so you need to go to the doctor and get more advice.
If you still have questions about anal acne, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
