Ear piercing is an invasive operation that destroys the soft tissues of the ear cartilage, and a short period of localized swelling after the trauma is a normal physiological phenomenon, which can be alleviated through regular disinfection of the ear piercing, use of anti-inflammatory medication, and attention to daily care and prevention of the symptoms of swollen ears, and prevention of infection. Patients can use iodophor or alcohol to disinfect their ears every day, or go to the hospital to have their ears disinfected by a doctor. Patients can also apply antibiotic ointment and erythromycin ointment when their ears are swollen and painful, which can help relieve the inflammation of the ear holes, reduce swelling and pain, and promote the repair of the trauma of the ear holes, and use oral antibiotics under the guidance of the doctor if necessary. In daily life, patients should also pay attention to the cleaning and care of the ear, regular cleaning and replacement of ear plugs, sleep in a supine position to avoid extrusion of the ear wound, causing inflammation to worsen. Pay attention to a light diet, less oil and less spicy. When the symptoms worsen and the pain is not relieved, it is recommended to go to the hospital for examination and cooperate with the doctor for relevant treatment.
