Lymph nodes - an important element of the immune system. These are the nodal structures located in the network of small vessels through which the fluid - lymph flows. Lymph nodes contain protective cells - lymphocytes. They are responsible for the production of antibodies and play an important role in the fight against infections and cancer. Consider the situation when the lymph node has inflamed under the jaw.
Why are the lymph nodes inflamed?
Lymph nodes are spherical formations of various sizes, scattered throughout the body from neck to groin. They act as filters, cleaning the lymph from toxins and harmful substances and preventing them from being absorbed by the cells of the body's tissues.
When an infection gets inside the lymph node, antibodies begin to reproduce in it, which causes inflammation. This is quite common, especially in children. The child’s immune system is still weak and, therefore, the body is more exposed to bacteria or viruses, and therefore the lymph node may be inflamed, for example, under the jaw.
Swollen lymph nodes can also be due to a sore throat. Most often, this phenomenon does not pose a serious danger and may be accompanied by other symptoms, such as fever or pain.
The main reasons for which the lymph nodes under the jaw can be inflamed include:
- Sore throat or, more correctly, pharyngitis caused by viruses or bacteria.
- Chronic lymphadenitis, which develops as a result of a bacterial infection.
- Chronic ENT diseases of a bacterial nature.
- Tonsillitis, that is, a viral or bacterial infection of one or both of the palatine tonsils, which are lymphoid organs in the throat.
- Flux characterized by inflammation of the gum pocket. And a quarter of all cases when the lymph node in the neck on the left below the jaw hurts, causes neglected caries of a multiple character.
- Infections of a specific nature, for example, parotitis or mumps.
Do not underestimate infectious diseases such as mononucleosis, which is caused by the herpes virus and leads to an increase in the number of white blood cells in the blood and toxoplasmosis. As a rule, the disease is transmitted to people from cats through contact with feces or by eating the meat of infected animals.
Even more disturbing are the accompanying increase in lymph nodes in the neck and other parts of the body such disorders in the body as lymphoma and malignant tumors. They originate in the lymph nodes and can then spread to other organs.
What symptoms can occur?
Let us consider in more detail what symptoms are accompanied by inflammation of the submandibular lymph nodes under certain conditions. So, with tonsillitis, there is a noticeable increase in lymph nodes with a rapid increase in pain. For 24-48 hours, signs of stiff neck appear, which does not allow you to turn your head freely. The skin that covers the knot becomes red and hot, the temperature rises. If the infection does not stop, an abscess of the lymph nodes of the neck may develop.
Early manifestation of mononucleosis is similar to tonsillitis with acute sore throat and high fever. Almost always, the disease is accompanied by a marked swelling of the lymph nodes under the jaw and in the neck, giving it a bovine appearance. Unlike normal tonsillitis, mononucleosis is always accompanied by serious changes in the composition of the blood. The patient has excessive fatigue and muscle pain.
Feline scratch disease - toxoplasmosis, unfortunately, quite a common infection, which is accompanied by a significant increase in lymph nodes in the jaw and neck, and sometimes high fever and abscess. Sometimes surgery is necessary to remove the affected node.
When mumps occurs unilateral generalized damage to the lymph nodes. For example, the lymph nodes are inflamed on the left under the jaw, on the face and neck. This condition is accompanied by high fever, difficulty swallowing and hearing impairment.
Edema of a malignant lymph node usually occurs painlessly with one-sided localization and is not accompanied by fever or other symptoms.
Inflammation of the submandibular lymph node: what to do?
What to do if the lymph node is inflamed under the jaw? First of all, do not panic, and you should immediately consult a doctor. Most often, the reason is found immediately, but sometimes it is necessary to pass blood tests and undergo an ultrasound of the neck. In fact, otolaryngologists are often sufficiently thorough palpation to get a complete picture of the pathological picture.
It should be remembered that the lymph nodes after inflammation need some time (from several weeks to months) in order to return to normal size. But when inflammation causes fibrosis of the lymphatic structure, the tumor can persist for many years without pathological significance.
How to treat an inflamed lymph node under the jaw? Since lymphadenitis is a consequence of the disease, therapy will depend on the main diagnosis:
- viral infections require treatment with antiviral drugs;
- antibiotics for bacterial infections;
- for candidiasis antifungal agents are used.
The duration of treatment and the dosage is set by the doctor and depends on the severity of the disease. In the case of an increase in body temperature above 38 °, apply antipyretic drugs. When tonsillitis, in addition to antibiotic therapy, local treatment is used to alleviate the condition of the inflamed tonsils. For the treatment of an inflamed lymph node under the jaw due to caries should consult a dentist.
As you can see, the inflammation of the lymph nodes cannot be ignored, since it can be a symptom of a serious disease. Take care and be healthy!
