If you are prone to frequent boils, or your boils do not go away with treatment, you should consult with a doctor to rule out any underlying conditions that may be causing your boils, such as undiagnosed diabetes, anemia or infection. Your doctor can also prescribe or recommend additional preventative measures. These could include oral antibiotics, topical treatments, and iron supplements.

Topical antibiotics can also be prescribed to apply to boil-prone areas, or open wounds. MRSA (methicillin-resistant Staphylococcus aureus) is a strain of staph that has become antibiotic-resistant, making it much harder to treat. It is often picked up in hospitals and other healthcare settings, such as nursing homes. However, it can also be spread by skin-to-skin contact, such as during sports activities. Boils occur with MRSA infections. Other signs to look for include abscesses (collections of pus in your skin), carbuncles (lumps that often contain pus and fluid), and impetigo (thick, crusted boils that...
