Swollen lymph nodes are usually treated by treating the underlying cause, as stated by WebMD. Antibiotics are always prescribed for bacterial infections that cause swelling of the lymph nodes. If it is cancer, a person will need to undergo a biopsy to clear any doubts.
In some situations, the lymph nodes may swell indicating that the body is fighting an infection. The soreness may clear up after several days, but it may take weeks for the lymph nodes to return to their normal sizes. Swollen lymph nodes that do not get better after a month may require a diagnosis to identify the cause.
Lymph nodes are located in all parts of the body and play a crucial role in the immune response of an individual. They help in identifying and fighting foreign invaders in the body. Lymphadenopathy is the name given to the condition whereby a person has swollen lymph glands in one or more places in their body.
Swelling of the lymph nodes can be caused by several causes, including skin infections, mouth sores, sexually transmitted diseases, gingivitis, mononucleosis, ear infections, cold and flu, impacted tooth, tonsillitis and tuberculosis. Cancers, such as leukemia, Hodgkin's disease and non-Hodgkin's lymphoma, also cause swollen lymph nodes. Swollen lymph nodes that appear suddenly can be as a result of an injury or an infection.
