15 Essential Oils For Swollen Lymph Nodes Behind Ear, In Armpit, Neck, Throat, and Groin

The lymphatic system is a network of vessels, organs, and lymph nodes situated throughout the human body.

Lymph nodes are clusters of cells, surrounded by a capsule. The lymph nodes play an important role in the body’s capacity to fight off infections.

They are actually glands which store white blood cells – cells of the immune system that move throughout the body, looking for invaders.

A lymph node is considered swollen if it measures approximately half an inch wide.

Common areas where swollen lymph nodes are more prominent include:

  • in the armpits;
  • under the chin;
  • the groin;
  • in the neck;
  • behind the ear.

A few mechanisms can cause the lymph nodes to enlarge, such as:

Cancercancer bacteria

  • cancer of the blood – malignant multiplication of lymphocytes as in leukemia or lymphoma;
  • skin cancers – they may spread first to the closest lymph glands to the area of skin involved;
  • stomach and lung cancers – they may spread to lymph glands which you typically cannot see or feel in the abdomen and chest;
  • throat cancer – it may spread to lymph glands in the neck;
  • breast cancer – it may spread to the lymph glands in the armpit.


Infiltration with inflammatory cells during inflammation in a region of a given lymph node.


There is an immune reaction to a generalized infection in the human body like viral infections which can occur with the common cold as well as with HIV.


Numerous types of infection can cause swollen glands, like a glandular fever or a cold.

This can increase the number of white blood cells, that multiply in response to stimulation with a foreign substance.


You can help to ease the symptoms by:

  • taking painkillers like ibuprofen or paracetamol;
  • reducing your stress levels;
  • spending time outside to boost vitamin D levels;
  • drinking plenty of fluids;
  • having a diet rich in fruits and vegetables;
  • avoiding alcohol and tobacco;
  • plenty of rest.
