Summarize the following:
Boils can rupture and allow bacteria into the wound, causing an infection. If untreated, an infection can lead to serious health issues. Signs of an infection include pus in or around the boil and red streaks in the skin around the boil. The area might also feel hot and more painful than it was before. If your boil starts to look infected, call your doctor immediately. Talk to your doctor before you go to an emergency room as you may be at risk of exposure to MRSA at a hospital. Boils will normally rupture on their own and then heal within a week or so. But if your boil persists and is unchanged after 2 weeks, talk to your doctor. They can examine your boil and recommend treatment options. They may prescribe a cream that can help get rid of the boil. Your doctor may decide to lance the boil themselves. Boils in certain locations can be particularly painful and bothersome. Your spine has thinner skin and a boil there can hurt and make it difficult for you to sleep. Boils on your face can be embarrassing and painful. Visit your doctor so they can help treat your boil. Boils on your spine can accidentally rupture while you sleep. See your doctor for treatment. If you have a boil or boils and you develop a fever, it could be a sign of a system-wide infection or a deeper medical issue. Go to an emergency room or an urgent health clinic so you can be checked out. Even a low-grade fever could be a sign of an infection.

Summary:
Call your doctor if you develop signs of an infection. See your doctor if your boil lasts longer than 2 weeks. Seek medical treatment for a boil on your spine or your face. Get medical help if you develop a fever.
