Symptoms

The irritation in and around your anus can be a temporary condition or it may continue to bother you. Pruritus ani produces itching, soreness, and burning.

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your doctor will try to determine the cause of your condition.

Treatment

Talk with your doctor about the best treatment plan for you. Ideally, the cause of the problem will be identified and treated. For example, antibiotics may be prescribed to treat an infection. Treatment for the itching and irritation may include:

Self-care

  • Wear loose cotton clothing and underwear
  • Avoid irritants (eg, bubble baths, certain foods)

Medication

  • Over-the-counter or prescription cream or ointment containing hydrocortisone or other corticosteroids to reduce itching and provide protection
  • Zinc oxide ointment—to provide protection
  • Topical capsaicin—to reduce itching
  • Certain medicines to treat infection if this is thought to be the cause of your itching

Prevention

  • Try to keep the area clean and dry
  • Avoid scratching at the area
  • Avoid using perfumes, dyes, and any other irritants on the area
