For a painful boil in this sensitive area, you can start by taking warm sitz baths (soaking in warm water for 15 minutes, three times a day) to soothe the area. You can apply a generic over-the-counter triple antibiotic ointment (containing bacitracin or polymyxin) to the skin, and take oral ibuprofen or paracetamol to manage the pain. Please do not try to squeeze or pop it. Because it hurts during bowel movements, it could be a perianal abscess, which often requires a quick, simple evaluation and drainage by a doctor. I highly recommend seeing a healthcare provider to ensure it heals safely and quickly.

Since blisters have formed, you have a second-degree burn. Please do not pop the blisters, as they protect against infection. For immediate relief: 1. Clean gently with mild soap and cool water. 2. Apply a thin layer of petroleum jelly (Vaseline) or an over-the-counter antibiotic ointment like Bacitracin. Avoid home remedies like butter or toothpaste. 3. Cover loosely with a sterile, non-stick bandage. 4. Take Ibuprofen or Acetaminophen to manage the pain and burning sensation. If the burn is larger than your palm, on your face or hands, or shows signs of infection (pus, increased redness), please see a doctor.
