Pus in the ear piercing is usually caused by bacterial infection, if the pus is small, it can usually subside on its own. If the pus is large and accompanied by symptoms such as redness, swelling, heat and pain, you should seek medical attention in a timely manner and not squeeze it by yourself, as this may cause the infection to expand and worsen the symptoms. Pus pockets in ear piercing may be caused by local inflammation due to unclean operation during ear piercing, which usually does not require special treatment. In addition, it can also be caused by folliculitis, with a central red papular pustule, accompanied by slight pain and itching, which can recover on its own if it is small. If the infection is severe, its pustules will gradually expand in scope and the small hard nodules will become soft and fluctuate. Over time, the pustules may shed and break down on their own, and may heal on their own within a few days. In addition, if the abscess is progressively enlarged, it is necessary to go to the ENT department of the hospital in a timely manner and make an incision and drainage treatment according to the situation.
