Can cartilage piercing cause lymph nodes to swell behind the ear?

Possibly yes: Auricle (outer ear) infection can cause nearby lymph node swelling. Auricle skin or cartilage infection from cartilage piercing is high risk. See an otology/ent md asap for antibiotic treatment.

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.
