This is so called boil. Your boil is due to repeated infection. Your proneness to infection depends upon your body immune system which fights against any such invading agent such as bacteria, virus and fungus. There are a number of factors which jeopardize your immune system resulting in increased susceptibility to infection. Those factors include
nutritional deficiency,
diabetes, and compromised skin integrity such as after surgery or trauma,
excessive sweating, and compromised blood circulation. Look at these aspects. You might find the cause of repeated infection in yourself.
