Why does a hard lump grow on my ear and it hurts?

A hard lump inside the ear should certainly not be ignored, because if it is caused by swollen lymph nodes, the impact may be greater. In addition, otitis media, scalp infection, etc. may also cause symptoms of multiple lumps.

1. Swollen lymph nodes

The hard lump behind the ear may be caused by inflamed and swollen lymph nodes. Normally, the lymph nodes cannot be clearly felt. When they are swollen, they feel like a hard lump, as if a hard lump has suddenly grown. Swollen lymph nodes may be caused by surrounding diseases, such as otitis media, scalp infection, etc. The lymph nodes themselves do not need to be treated, just the primary disease. If the primary disease is unknown, you can observe it first. If the hard lump does not shrink over a long period of time, it is recommended to see a doctor.

2. Sebaceous cyst

In addition to swollen lymph nodes, it may also be a sebaceous cyst. If the sebaceous gland excretion duct is blocked, the sebaceous gland cystic epithelium will be expanded by the gradually increasing contents to form a retention cyst. Sebaceous cysts occur slowly, are round in shape, have clear boundaries with the surrounding tissues, are soft in texture, are non-tender, and are movable. Generally no symptoms. Sebaceous cysts are usually removed surgically under local anesthesia. Sebaceous cysts are more common in teenagers, especially unmarried men. Because they are in adolescence, they are energetic and have strong secretions. Therefore, if sebum is not cleaned in time, it is easy to accumulate behind the ears, which will form sebaceous cysts over time. It's like there's a hard lump behind the ear.

3. In general, pay attention to hygiene in daily life and remember to clean the surface of the ears when washing your face, and it will disappear without treatment. If the sebaceous cyst is abnormal, do not rush to treat it yourself. You must go to the hospital for diagnosis. If the doctor wants to remove it, it will be a relatively minor operation.
