What causes swollen lymph nodes under the ear? Don't ignore

Swollen lymph nodes are a common phenomenon in daily life. Only the swollen area will feel painful, and it has no effect on people's other activities. Therefore, it is easy to be ignored by people, leading to very serious consequences. In fact, there are reasons for swollen lymph nodes. Let’s take a look at what causes swollen lymph nodes under the ears!

Swollen lymph nodes under the ears are caused by inflammation in the body, which means that you have been nervous or anxious recently and under a lot of pressure. The body's immune system's lymph nodes are gathering together to eliminate bacteria. You need to take anti-inflammatory drugs. The swollen area may be painful. This is caused by the accumulation of lymphocytes and compression of the nerve endings on the surface of the skin. But don't rub them with your hands. Eat a light diet these days. Don't eat greasy food, spicy food, seafood, various kernels such as melon seeds and peanuts, and don't let the swollen area be exposed to the wind.

There are four main causes of swollen lymph nodes:

1. Inflammatory swelling

Acute and chronic lymph node infections caused by bacteria, viruses, rickettsia, chlamydia, fungi, spirochetes, protozoa, worms, etc. can cause lymph node enlargement.

2. Tumorous swelling

Cancer metastasis usually occurs in the lymph nodes, so be careful.

3. Reactive hyperplasia and swelling

Lymph nodes swell because the body is irritated.

4. Histiocytic hyperplasia and swelling

There is a large amount of tissue cell proliferation in the lymph nodes, which is distributed in a focal or diffuse manner, and granulomas may also form, such as Langerhan histiocytosis. In addition, there are a large number of Niemann-Pickz cells in the lymph nodes, and when Gautier cells aggregate, they can also cause lymph node enlargement, such as Niemann-Pickz disease, Gautier disease, etc.

Therefore, the above may be signs of swollen lymph nodes. Whether it is swollen lymph nodes behind the ears or others, a thorough diagnosis is required to find out the cause.
