Blackheads are a type of acne in which the pores in the skin gets filled with dead skin, causing it to turn black. They are very common in everyone but usually seen in people that have oily skin. Infected blackheads are usually seen on the nose and forehead even though they can occur on any part of the body.
Blackheads can be easily cured if the person maintains a good hygiene and exfoliates his/her skin regularly, but in some cases of carelessness, the blackheads get infected. These can be very painful if the infection increases and sometimes small operations need to be done to cure them. Even though the blackhead infection is not very serious but, if mishandled, the microbes causing them can enter the blood vessels and cause an even bigger infection. Blackheads can develop in any part of the body, even in the ear canal or the eyelids and cause intense pain if infected.
Contrary to the popular belief that squeezing a blackhead cures it, this can cause it to get infected. The popping of the blackhead might lead the dirt and bacteria to get trapped in the skin. This leads to the skin becoming infected. Especially if the blackhead is squeezed with dirty hands and proper hygiene is not maintained, pus-filled bumps start forming. After the pus filled bumps are formed, if they are squeezed before maturing completely, there is a possibility of the infection spreading to the blood and the doctor might have to operate the area to treat it.
