Bumps on the ear should be clear about the location, nature and size, and then further clarify the cause of the disease. If it is the earlobe of the pimple most commonly seen in the ear lip cyst, sebaceous gland infection, etc., the initial stage of local povidone-iodine disinfection and pay attention to the ear hygiene can generally be relieved on their own. If it cannot recover by itself, pus or infection can be incised and drained locally, paying attention to the disinfection of the wound and changing the medicine, as well as oral antibiotic treatment to prevent infection. If it is the skin behind the ear, it is mostly seen in the swelling of lymph nodes behind the ear, which is divided into infectious and tumor diseases. If it is caused by otitis media, gingivitis, upper respiratory tract infection, tonsillitis and other diseases, mostly due to infection leading to the suppression of pain, active treatment of the original disease after the lymph nodes can gradually reduce. If it is caused by head and face tumor, lymphoma, leukemia and other malignant diseases, the lymph nodes behind the ear are mostly painless and enlarged, and most of them are found by the primary disease or unintentionally, the prognosis is relatively poor and difficult to recover, and the cause should be clearly defined and then given treatment.
