When your hair follicles are inflamed and infected, then this condition is known as boils. It is very painful. In their early stage, they are tender and red lumps. These lumps are filling with pus. When this process is happening, then the lumps are growing more and they are becoming painful till the moment in which they rupture and drain. This condition can be treated at home. You should know that boils should not be pricked or squeezed because you can make your infection bigger. If you feel that your boil is painful than before, then you should visit your doctor. Also if your boil is associated with fever and it lasts more than two weeks, you should visit your doctor. They can appear everywhere on your skin.
