What Is a Perianal Abscess?
A perianal abscess is a painful pocket of pus that forms around the anus when one of the tiny anal glands becomes blocked and infected. If left untreated, it can enlarge, cause systemic signs of infection (fever, chills), and lead to more serious complications such as fistula formation.
Diabetes or other conditions that weaken the immune system
Poor anal hygiene or local trauma
History of previous abscesses or fistulas
Signs and Symptoms
Sharp, throbbing pain near the anus, often worse when sitting
Redness and swelling or a tender lump around the anal opening
Fever or chills
Pus or blood draining from the affected area
General fatigue or feeling unwell
How Dr. Scott Diagnoses a Perianal Abscess?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptoms, medical history (e.g., Crohn's disease, diabetes, past abscesses) and performs a gentle rectal and perianal exam to identify warmth, swelling or discharge.
Laboratory Tests
A complete blood count checks for elevated white blood cells, indicating an active infection.
Imaging Studies
High-resolution ultrasound visualizes fluid collections beneath the skin around the anus.
Pelvic MRI with contrast maps deep abscesses and any associated fistula tracts.
Fistula Evaluation (if needed)
For recurrent or complex cases, Dr. Scott may perform an endoanal ultrasound or fistulogram to trace any hidden fistulous connections.

Frequently Asked Questions
When should I see a doctor about a perianal abscess?
Seek medical attention as soon as you notice pain, swelling, redness, or fever near the anus. Early evaluation by Dr. Scott helps prevent the infection from spreading and speeds healing.
Can a perianal abscess heal on its own?
No. A perianal abscess requires drainage to resolve properly. Without professional intervention, it can worsen or lead to deeper infections.
What is the treatment plan for a perianal abscess?
The standard approach includes incision and drainage, antibiotics to clear infection, and stool softeners to reduce straining. Follow-up care ensures proper healing and checks for any complications.
Can I avoid surgery for a perianal abscess?
Many patients are treated with in-office incision and drainage, which is minimally invasive and often avoids hospital admission. Dr. Scott will recommend the least invasive option tailored to your condition.
Will I need to stay in the hospital?
Most perianal abscesses are treated on an outpatient basis at our clinic. Hospitalization is rarely needed unless the infection is extensive or you have other serious health issues.
Can diet help prevent perianal abscesses?
Yes. A high-fiber diet, adequate hydration, and proper hygiene reduce constipation and straining, lowering your risk of developing anal gland blockages and abscesses.
What if the abscess comes back?
If an abscess recurs, Dr. Scott will evaluate you for underlying causes such as fistulas or Crohn's disease. He'll then adjust your treatment plan, which may include seton placement or advanced imaging.
