Swollen Lymph Nodes (Glands)  

Transient enlargement for 2-3 days may occur with an infection in the head and neck such as tonsillitis, skin or ear infections. The site of the swellings indicates the area drained by the nodes and is a guide to the source. If nodes are persistently enlarged you should consult a doctor. The possible causes include infections (viruses, bacteria or others), tuberculosis, lymphoma and cancers of the head and neck.
