What is the cause of the lymph nodes behind the baby's ears?

Many babies suffer from diseases that seriously affect their development and growth. Therefore, many babies need timely treatment to ensure the baby's safety, especially timely treatment. So what is the matter with the baby's lymph nodes behind the ears? Let me introduce this issue to you below.

Sometimes you can feel lumps of varying sizes behind the ears, neck, under the jaw, and at the base of the thighs of children. Most of them are mobile and can slide under the skin. These small lumps are lymph nodes. Because lymphatic tissue, especially lymph nodes, develop rapidly within one year of age, healthy children may feel lymph nodes in superficial parts of the body such as behind the ears, neck, under the jaw, armpits, and groin (i.e., groin). However, the lymph nodes in these areas are normally no larger than soybeans, are mostly single, soft in texture, can slide under the skin, are painless, and are not adhered to surrounding tissues. However, lymph nodes should not be palpated under the chin, supraclavicular fossa, or elbows.

In some abnormal cases, lymph nodes may also become abnormally swollen. Because lymph nodes can produce lymphocytes in the blood, these lymphocytes have the function of defending against bacteria. The lymph nodes in various parts of the body are connected to nearby organs or tissues by lymphatic vessels, just like "sentry posts" around the body. When nearby tissues or organs are attacked by bacteria, they can kill the bacteria and prevent them from spreading outward. As a result, the lymph nodes themselves become enlarged, can be felt, and may be painful or tender. Therefore, the location of the bacterial infection lesion can be inferred from the location of the swollen lymph nodes. For example, enlarged submandibular lymph nodes may be caused by inflammation of the oral cavity and pharynx, and enlarged occipital lymph nodes may be caused by inflammation of the skin on the head and back of the neck.

The above is my opinion on this issue. If the child has the above problems, the patient should pay special attention to the treatment, especially to ensure the safety of the child, and then adopt the doctor's method to carry out corresponding treatment. This will ensure the safety of the child and the effectiveness of the treatment. Finally, I wish the child a speedy recovery.
