Why might I keep getting boils?

Boils are painful, inflamed, pus-filled lumps that can affect any part of your skin. They most commonly develop in an infected hair follicle, especially in areas where there is sweat or friction, so the face, neck and thighs are particularly susceptible.

Boils usually develop as a consequence of bacteria called staphylococcus aureus ('staph') causing infection. These bacteria can live harmlessly on skin until they enter into skin via a graze or wound.

You're at higher risk of boils if you are obese, have other skin conditions such as eczema, a weak immune system, or an underlying condition like diabetes. Close contact with a person who has a boil can also increase your risk.

To reduce the risk of developing or passing on a boil consider these simple steps:

• Use antibacterial soap
• Wash your hands thoroughly, especially after touching infected body areas
• Clean cuts and wounds thoroughly and cover them with a sterile dressing
• Use a separate flannel and towel, don't share these
• Wash sheets, pillowcases and towels at a high temperature
• Disinfect high-traffic areas like doorknobs and light switches
• Avoid saunas, gyms and swimming pools when you have open cuts
• Eat well and exercise to support your immune system.

Don't ever squeeze or try to lance a boil yourself as you can make it worse and cause scarring. Most boils can be treated at home and go away on their own. Home treatment includes applying a warm flannel as a compress for 10 minutes, 3 or 4 times a day, taking painkillers for pain relief, and keeping the boil covered with a sterile dressing once it bursts.

If you get recurrent boils and haven't done so already, have a check-up with your GP. He or she may arrange blood tests or skin swabs to rule out other types of infection, and check for underlying causes like diabetes. In severe cases, he or she may also recommend a course of antibiotics.
