The most common cause of swollen lymph nodes is an infection, particularly a viral infection, such as the common cold. However, there are other types of infections, including parasitic and bacterial, and other possible causes of swollen lymph nodes.They include:ymph nodes are located in groups, and each group drains a specific area of your body. You may be more likely to notice swelling in certain areas, such as in the lymph nodes in your neck, under your chin, in your armpits and in your groin.
Which lymph nodes become swollen can sometimes help track which diseases are creating the problem. Lymph nodes become swollen usually from bacterial or viral infections. As bacteria or viruses invade the nodes, they harden and inflame, and they can really begin to hurt. With colds and flus, you may note painfully swollen nodes around the throat, under the arms and at the groin.
