How to treat a boil
Make sure that the boil is actually a boil.
Before you begin treating a boil, it is important to make sure that what you have is actually a boil. Boils are caused by an infection of your hair follicles with staphylococcus aureus.
They are contagious and they can spread to a different part of your body or to someone else who comes into contact with your boil. Boils may be mistaken for cysts or have cysts beneath them, which requires treatment by a doctor.
