What are sore swollen lymph nodes?
the lymphatic system is the system in the body used to filter out infection and bad bacteria that are harmful to the body, when a lymph node is swollen it is often being overworked and is trying to fight an infection. Typically when you have a swollen lymph node, there is some underlying infection that will either be fought off, will show itself in a less severe form, or will completely beat out the lymphatic system and you will get the full blown sickness.
