Boils are nothing, but a skin disease, caused by the infection of hair follicles. The problem is usually caused by Staphylococcus, a strain of bacterium that normally lives on the skin surface. While some boils which come and fade away on their own, without causing any trouble, others last a long time and cause pain and irritation. Face, shoulders, back, buttocks and underarms are the regions where boils usually occur. Boils do not come instantly. At first, the affected area becomes red and soft. There may be an itching sensation as well. Slowly, the boil begins to form. The bacteria that cause boils might also mix with the white blood cells, resulting in the formation of pus. Boils can be cured using some home remedies. Not only do they provide instant relief but also remove the boil completely.
