Most people's natural immune systems are strong enough to effectively deal with minor skin infections such as boils. Thus, boils often heal on their own after a period of a few weeks, although you'll likely experience some itching and mild throbbing pain in the early stages. Boils can become more painful with time as the pressure builds up from pus accumulation, although they can spontaneously burst after a few weeks and then clear up quickly.  If you are anticipating a boil bursting on its own after a few weeks, be prepared by carrying some antibiotic wipes and clean tissues with you or in your car. If you have a boil on your face, keep it clean and refrain from covering it up with a thick layer of make-up or cover-up. Facial boils can be embarrassing, but it’s  best to expose them to the air and let your immune system deal with them. Applying a warm washcloth or flannel compress to your boil helps to rupture and drain it because the heat expands the blood vessels underneath the skin and increases blood and lymph flow. The warmth may also help sooth the pain, even though it’s promoting local inflammation. Soak a clean washcloth in water and put it in the microwave for between 30-45 seconds. Apply the warm compress to the affected area several times daily (for about 20 minutes at a time) until the boil starts to naturally drain and shrink.  Be sure to wash and rinse the towel once you are done to avoid spreading the infection, although microwaving it will likely kill any bacteria anyway. Make sure the cloth from the microwave doesn't scald your skin and make the problem worse. Tea tree oil is a natural antibiotic/antiseptic commonly used to treat skin infections — it's extracted from the leaves of the Australian tea tree. Tea tree oil may help get rid of boils because it has anti-inflammatory and antibacterial properties, although the degree to which it can absorb deep into the skin is not well understood. It's also useful for preventing the spread of the bacteria once the boil has burst. Use a clean swab,...
