Why are the lymph nodes inflamed?

By lymph node is meant a small clump of cells that are covered by connective tissue. Such cells are considered a combination of lymphocytes, which produce proteins and also protect the body from foreign invasion, for example, viruses.

As a rule, the lymph nodes are located in groups, with each of them cleans only a certain part in the body. The main cause of their inflammation is viral infections, the common cold or flu. However, there are also other infections that are parasitic and bacterial in nature. This largely explains why the lymph nodes are inflamed in the neck, in the armpits, in the groin or under the chin, since these places are the source of infection. The process during which they inflame is called lymphadenitis.

There are characteristic symptoms that indicate why the lymph nodes are inflamed:

  • Swollen and swollen limbs are a sign of a possible blockage of the lymphatic system. As a result of this, inflammation of the lymph nodes that are deep under the skin occurs, so their increase is difficult to see with the naked eye.
  • Infections of the upper respiratory tract cause, as a rule, inflammation of the lymph nodes in the neck and under the chin. In this case, the patient may increase body temperature or excessive sweating.
  • Less consolatory are signs of hardened and rapidly increasing lymph nodes. This can cause a tumor of a different nature.
  • If a person suffers from inflammation of the lymph nodes throughout the body, then most likely this can be a sign of serious diseases, including lupus, rheumatoid arthritis and even HIV.

Consider the reasons that indicate why the lymph nodes are inflamed in the groin and with which infections it may be due:

  • Possible injury;
  • Infections that affect the lower limbs and genitals;
  • Malignant or benign tumors;
  • Genital and viral infections, including toxoplasmosis, tuberculosis, which are transmitted sexually.

We will also explain why the lymph nodes are inflamed under the armpits. An enlarged lymph node under the armpits causes a series of creepy assumptions about its nature of occurrence. Note that this phenomenon does not always indicate a tumor. In most cases, the lymph nodes are inflamed due to infections, which can be either bacterial or parasitic or fungal.

To restore the former size of the lymph nodes, it may be sufficient to apply a warm compress to them, but in special cases prescription drugs may also be required. In this case, after detecting an enlarged lymph node, the armpit needs to consult a doctor who can establish an accurate diagnosis and the reason for its occurrence. Note that often the diseases that caused the inflammation of the lymph node can lead to serious complications, such as infertility, loss of vision, hearing, etc.
