What is the cause of the hard lump behind the child's ear?

Recently, many mothers have discovered that their children have hard lumps behind their ears. This has made the mothers very anxious. What is going on? Don't worry, this is called swollen lymph nodes. This time we will help these mothers solve the mystery and see what the true appearance of this lump that worries us is.

Lymph nodes are found all over the body, especially near the neck. There are many lymph nodes, and there are also lymph nodes behind the ears. What is the cause of swollen lymph nodes behind the ears? What are the hazards?

Lymph nodes are found throughout the body, including behind the ears. So why do healthy lymph nodes swell? Are there any hidden dangers in swollen lymph nodes? Or is it a sign of a physical illness?

Unexplained enlargement of the cervical and supraclavicular lymph nodes indicates a systemic lymphoproliferative disease and should be taken seriously and further examined and confirmed.

In fact, swollen lymph nodes can be a very small case, which is a general bacterial infection causing an inflammatory reaction. This type of swollen lymph nodes is easier to solve. For example, swollen submandibular lymph nodes are mostly caused by inflammation of the mouth and throat. It can be treated with external application of Chinese medicine. Prunella vulgaris is used by many patients. Swollen lymph nodes behind the ear may also be caused by bacterial infection.

However, swollen lymph nodes can also be a sign of physical disease. Just like the incidence of lymphoma has been gradually increasing recently, swollen lymph nodes is the biggest sign.

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.

After the above introduction, do we have some understanding of this disease? At the same time, I would like to remind all mothers here not to rush to seek medical treatment just because the baby has a minor problem. This will cause you to panic. This will be bad for the baby. I hope our information can help you.
