Lymph Node Swellings


Lymph Node Swellings

Lymph nodes are small, bean-shaped glands present throughout your body, that helps with protection against germs. Swollen lymph nodes are a primary sign that indicates the body fighting off an infection or illness. Most of the time, they return to their normal state once the condition has been taken care of.
Lymph nodes can swell up for a variety of reasons ranging from mild to severe. Mild causes include viral or bacterial infections such as cold, ear infections, etc.
More severe reasons for lymph nodes to swell up can include:
  • Tuberculosis
  • Problems with your immune system, such as lupus
  • Certain types of cancers, such as lymphoma or leukemia
  • Less common infections eg Lyme disease, HIV
Lymph node swellings which do not spontaneously resolve, keep enlarging or cause pain and skin discolouration are best investigated by an ENT doctor. Evaluation of the head and neck region is paramount followed by a biopsy of the lymph node to ascertain its nature.
