There's a lump under my ear.

If there is a hard lump under the ear, it cannot be ruled out. It may be a cyst or lipoma. If there is a swollen lymph node behind the ear, it will also show such symptoms. Therefore, when such a situation is shown, it must go to a regular hospital for examination and clear the cause and symptomatic treatment. If the lymph nodes behind the ear are swollen, more common is to show inflammatory hyperplasia. If there is no obvious increase or other uncomfortable symptoms, you can temporarily observe them first. If there is a significant increase in the phenomenon, then you need to go to the hospital to do a color ultrasound examination, and then symptomatic treatment according to the results. If the symptoms caused by factors such as sebaceous cysts or lipomas, surgery can be performed after the lesions gradually grow.
