Swollen lymph nodes in the neck are most commonly caused by infections like colds, flu, strep throat, mono, or tooth/ear infections, as they filter out germs; they can also result from autoimmune conditions (lupus, rheumatoid arthritis), certain medications (seizure drugs), or, less commonly, cancers (lymphoma, leukemia, or metastatic cancer). The swelling indicates your immune system is fighting something nearby, like a head or throat issue, and usually resolves as the infection clears.
