Many areas: Not sure where the location of the lymph node is? On the back of what? Usually an enlarged lymph node with swelling and pain could be a sign of infection. Any infection in the head and neck can cause this and the sinuses is one of many areas. Please consult your md asap for an evaluation.

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.

The lymphatic system monitoring infection above the neck includes the tonsils, under the tongue and the swelling can be felt just below your jaws, along the muscles of the neck and the armpits.
