Things you can do to help boils

There are things you can do to treat boils yourself and stop them coming back.

Do

  • soak a flannel in warm water and hold it against the boil for 10 minutes 4 times a day

  • clean the area around the boil with antibacterial soap if pus comes out

  • cover the area with a dressing or gauze until it heals

  • bathe or shower every day and wash your hands regularly

  • take paracetamol or ibuprofen to ease the pain

  • wash your towels and bedding at least once a week at a high temperature

  • try to lose weight if you are very overweight and have boils between folds of your skin

Don’t

  • do not pick, squeeze or pierce a boil

  • do not share your towel with other people

  • do not go to a swimming pool or gym until the boil has gone –⁠ you could pass the infection on to others

    If you are currently being treated for a skin infection that has not improved after 2–3 days of antibiotics, return to your doctor.

    Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is a strain of staph bacteria resistant to antibiotics in the penicillin family, which have been the cornerstone of antibiotic therapy for staph and skin infections for decades. CA-MRSA previously infected only small segments of the population, such as health care workers and persons using injection drugs. However, CA-MRSA is now a common cause of skin infections in the general population. While CA-MRSA bacteria are resistant to penicillin and penicillin-related antibiotics, most staph infections with CA-MRSA can be easily treated by health care practitioners using local skin care and commonly available non-penicillin-family antibiotics. Rarely, CA-MRSA can cause serious skin and soft tissue (deeper) infections. Staph infections typically start as small red bumps or pus-filled bumps, which can rapidly turn into deep, painful sores. If you see a red bump or pus-filled bump on the skin that is worsening or showing any signs of infection (ie, the area becomes increasingly painful, red, or swollen), see your doctor right away. Many people believe incorrectly that these bumps are the result of a spider bite. Your doctor may need to test (culture) infected skin for MRSA before starting antibiotics. If you have a skin problem that resembles a CA-MRSA infection or a culture that is positive for MRSA, your doctor may need to provide local skin care and prescribe oral antibiotics. To prevent spread of infection to others, infected wounds, hands, and other exposed body areas should be kept clean, and wounds should be covered during therapy.

    What does it look like when a boil comes to a head?

    As a boil matures, it grows larger, and its center fills with pus. This pus-filled center is called the core. Eventually, the boil comes to a head, meaning a yellow-white tip develops on top of the core.

    What to do when a boil has a head?

    When the boil starts draining, wash it with an antibacterial soap until all the pus is gone and clean with rubbing alcohol. Apply a medicated ointment (topical antibiotic) and a bandage. Continue to wash the infected area two to three times a day and to use warm compresses until the wound heals.

    How long for a boil to come to a head?

    Usually within 24 hours, the lump fills with pus and looks round with a yellow-white tip. Pus or other fluid may drain from the boil.

    Can you squeeze a boil with a head?

    When the boil bursts, cover it with sterile gauze or a dressing. This is to prevent the spread of infection. Afterwards, wash your hands thoroughly using hot water and soap. Never squeeze or pierce a boil because it could spread the infection.
