  • The lymphatic system is structured similarly to blood vessels.
  • They defend our immune system.
  • Lymph nodes have different shapes and sizes. For example, under the jaw, are flat, bean-shaped and are about 1 cm. The nape of the neck are about 0.5 cm in lentil shape, and the crotch is broad and a little more than 1.5 centimeters.

  • Normal infections due to colds, flu, tonsillitis.
  • Specific bacterial infections: syphilis, tuberculosis, salmonellosis.
  • Lupus infection.
  • Viral infections such as rubella and measles.
  • Infections with other pathogens, such as malaria or leishmaniasis.
  • Rheumatic diseases.
  • Inflammation of the lymph nodes due to medications such as perchlorate, cotrimoxazole, hydantoin.
  • Stress, poor sleep, poor diet, lack of nutrients.
  • Lymph nodes can, on occasion, cause inflammation of tumors that are treated in large proportions, such as benign (non-cancerous) neoplasms. However, we must consider that the risk of emergence of so-called malignant lymphomas exists, and that each of the changes we feel and symptoms, should be evaluated by a physician.

Diagnosis of Swollen Lymph Nodes Neck:


Consult a physician, we will have the proper diagnosis and treatment. However, the doctor will always consider some factors and ask the following questions:

  • Have you had a cold or the flu?
  • In what region did the ganglion swell? Neck, armpit, clavicle?
  • When did you notice? Did it show up fast or did it grow slowly?
  • Does it hurt on the spot?
  • Have you had diseases before the onset of inflammation?
  • Do you take any medicine?
  • Did you travel recently?
  • Have you lost a lot of weight recently?


All this will allow the doctor to detect the problem, since most of the time the inflammations in the ganglia arise due to previous diseases, when our immune system is not yet fully recovered.



In some cases, they arise due to some medication or some bacteria, but with our help and the relevant tests, the doctor can explain the cause of the inflammation.

Data to be considered:

This type of inflammation is not so dangerous, but it is necessary to control it so that it does not develop, becoming large: when it passes 4 cm, it is necessary to perform a biopsy to know what exactly it is and how serious it is.



Also remember that just as the neck lymph nodes are usually harmless, those on the clavicle, regardless of their size, are always considered dangerous and it is imperative to treat them quickly because they can develop carcinogenic processes.
