Summarize this article in one sentence.
A towel that's warmed to 37-40 °C (100-105°F) may be applied 3-4 times a day for no more than 10-30 minutes. This dilates the blood vessels and the warm sensation diminishes the pain by acting as a counter-irritant that masks the pain brought about by the inflammation. Sebaceous cysts may be covered if not causing the patient distress; most are non-dangerous and are only bothersome aesthetically. However, if it's infected, seeking medical treatment is wise. Be sure to routinely and thoroughly wash the skin with non-irritating antimicrobial soap in running water. Pat dry the skin using a clean cloth or towel and cover with a sterile gauze – keep the gauze dry at all times. Avoid putting cosmetics and skin care products on the site of the cyst. This may cause further irritation and infection. This type of cyst dries up naturally; trying to pop it would put you at risk for further infection and may cause permanent scarring. Resist the temptation -- if it bothers you, get it removed by a doctor. If a cyst burst due to healing or accidental popping causing a break in the skin; wash the area thoroughly in running water using a non-irritating antimicrobial soap. If signs of infection occur -- pain, swelling, redness, and warmth sensation -- notify your doctor immediately for appropriate medical intervention. It's a very routine procedure and nothing to worry about; however, if left alone, you can become septic, which is a very, very serious condition. Even if your cyst doesn't seem infected, you may wish to visit a doctor. A very simple incision will be made, and the cyst can be gone in a matter of minutes. You may need to get 1 or 2 stitches once the cyst is removed.
Use a warm compress over the cyst. Keep the cyst clean. Never pop the cyst on your own. Seek medical intervention if there's a noticeable infection.
