Boils are painful, red bumps filled with pus that form under your skin when bacteria infect a hair follicle. The short answer is yes, many boils do go away on their own, but it is not always a simple wait-and-see situation. Most small boils will drain and heal without medical treatment within one to two weeks, but larger or more severe infections often need a doctor’s help to heal properly and prevent complications.
What Exactly Is a Boil and Why Does It Form?
A boil, also called a furuncle, starts when Staphylococcus aureus bacteria enter your skin through a tiny cut or hair follicle. Your immune system sends white blood cells to fight the infection. This battle creates pus, which is a mix of dead bacteria, dead skin cells, and white blood cells. The pus builds up pressure under your skin, which causes the pain and swelling.
Boils can appear anywhere on your body, but they are most common on the face, neck, armpits, shoulders, and buttocks. These are areas where you sweat more or where skin rubs against clothing. The CDC reports that about 30 percent of people carry staph bacteria in their nose without getting sick, but a break in the skin gives the bacteria a way in.
Some people are more prone to boils than others. If you have diabetes, a weakened immune system, or a skin condition like eczema, your risk goes up. Close contact with someone who has a staph infection also raises your chances. Poor hygiene and tight clothing can contribute, but they are not the main cause for most people.
Do Boils Go Away On Their Own or Do You Need Treatment?
Small boils, those about the size of a pea or a small marble, often resolve without any medical intervention. The body’s immune system fights the bacteria, and the boil eventually comes to a head, drains, and heals. This process usually takes 7 to 14 days from when the bump first appears.
There is a difference between a boil that drains on its own and one that needs help. When a boil drains naturally, the pain decreases almost immediately, and the swelling goes down over the next few days. The skin then heals over the opening. This is the ideal outcome for a boil that resolves on its own.
However, not all boils follow this path. Some become larger and more painful without ever draining. Others may drain partially and then close up, trapping infection inside. In these cases, the boil will not go away on its own, and waiting longer only makes things worse. A 2018 study published in American Family Physician found that about 60 percent of simple boils treated with home care alone resolved without complications, but the remaining 40 percent required some form of medical drainage or antibiotics.
What Are the Signs a Boil Needs Medical Attention?
Knowing when to stop waiting and see a doctor is important. A boil that does not drain after two weeks is unlikely to drain on its own. If the pain becomes severe, or if the redness spreads beyond the boil itself, the infection may be moving into deeper tissue.
Fever is a clear warning sign. If your temperature goes above 100.4°F while you have a boil, the infection may have entered your bloodstream. Chills, fatigue, or red streaks radiating from the boil are also signs of a spreading infection called cellulitis. The American Academy of Dermatology states that any boil on your face or spine requires immediate medical attention because of the risk of the infection spreading to your brain or spinal cord.
Boils that keep coming back in the same spot or multiple boils at once also need a doctor’s look. This condition, called furunculosis, often requires a prescription antibiotic and sometimes a test to see what type of bacteria is involved. People with diabetes or a weakened immune system should see a doctor at the first sign of a boil rather than waiting.
What Home Care Actually Works for a Boil?
If you decide to wait and see if a boil resolves on its own, there are steps you can take that help, and some that hurt. The most effective home treatment is applying a warm compress. Soak a clean cloth in warm water, not hot, and press it against the boil for 15 to 20 minutes three to four times a day. The heat increases blood flow to the area, which helps your immune cells reach the infection faster.
Warm compresses also encourage the boil to come to a head and drain. Once it drains, keep the area clean with soap and water. Cover it with a sterile bandage to prevent the pus from spreading bacteria to other parts of your skin or to other people. Change the bandage every day or sooner if it gets wet or dirty.
There are things you should never do. Do not squeeze, pop, or lance a boil yourself. This pushes the infection deeper into your skin and can cause a much worse infection. A 2020 review in Clinical Infectious Diseases noted that self-lancing a boil increases the risk of sepsis and scarring significantly. Do not apply over-the-counter antibiotic creams unless your doctor tells you to. These creams do not penetrate deep enough into a boil to reach the infection.

What Does a Doctor Do for a Boil That Won’t Go Away?
When a boil needs medical treatment, the most common procedure is incision and drainage. The doctor numbs the area with a local anesthetic, makes a small cut in the top of the boil, and lets the pus drain out. This provides almost instant pain relief for most people. The wound is left open slightly and packed with gauze to keep it draining for a day or two.
Antibiotics are not always needed after drainage. If the boil is simple and the person is healthy, drainage alone is often enough. The Infectious Diseases Society of America recommends antibiotics only when there is surrounding cellulitis, when the person has a fever, or when the boil is in a sensitive area like the face. When antibiotics are prescribed, a 7 to 10 day course is typical.
For people with recurring boils, a doctor may order a culture of the pus to identify the exact bacteria. This helps determine if the infection is MRSA, which is a type of staph that resists many common antibiotics. MRSA boils require different antibiotics and sometimes a longer treatment plan. A 2021 study in JAMA Dermatology found that about 25 percent of boils seen in outpatient clinics are caused by MRSA, so this is not a rare situation.
Common Misconceptions About Boils
One of the most common myths is that boils are caused by bad blood or eating the wrong foods. There is no clinical evidence that diet alone causes boils. While poor nutrition can weaken your immune system over time, a single boil is not a sign that your blood is dirty or that you ate something wrong.
Another widespread belief is that you can draw out a boil with home remedies like applying raw onion, garlic, or egg whites. Some people report that these help, but there is no strong evidence that any of these work better than a warm compress. In some cases, putting raw food on broken skin can introduce new bacteria and make the infection worse.
Some people think that once a boil drains, the infection is gone. This is not always true. If the boil was large or deep, there may still be bacteria in the surrounding tissue. Keeping the area clean and covered for several days after drainage is important to prevent the boil from returning or a new one from forming nearby.
- Warm compresses are the only home treatment with solid evidence behind them
- Squeezing a boil is the single worst thing you can do at home
- Clean bandages after drainage prevent the infection from spreading
- Hand washing before and after touching a boil reduces bacterial spread
- Separate towels and washcloths from others until the boil heals completely
How to Prevent Boils From Coming Back
If you have had one boil, you can take steps to lower your chances of getting another. Keeping your skin clean and dry is the foundation. Shower regularly and use an antibacterial soap on areas where you tend to get boils. Do not share razors, towels, or athletic equipment with others.
If you shave areas where boils appear, use a clean razor every time. Shaving creates micro-cuts that bacteria can enter. Shave in the direction of hair growth, not against it, to reduce irritation. Some people find that using a trimmer instead of a razor reduces their boil frequency.
For people with recurrent boils, some dermatologists recommend a short course of a nasal antibiotic ointment. This is because the staph bacteria often live in the nose and can be transferred to the skin by touching your face. A 2019 study in British Journal of Dermatology found that using mupirocin nasal ointment twice a day for five days reduced the recurrence of boils by 50 percent over six months. This is something to discuss with your doctor, not something to try on your own.
