Infection????: I would recommend you see your medical doctor and have them evaluated. Make sure it is the lymph nodes for starters. The lymph nodes are your bodies filters. Something is causing them to swell, you need to find out why.

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
