lymphadenopathy(lim″fad″ĕ-nop′ă-thē) [ lymph- + adenopathy]
Enlarged LNs may be tender or not; tenderness often is present when lymph nodes swell rapidly (e.g., in response to infections, hypersensitivity reactions, or some fulminant lymphomas). Rock-hard, enlarged, and immobile LNs are typical of metastatic cancer, whereas rubbery LNs are found in lymphomas. LNs that do not resolve spontaneously within 4 to 6 weeks, or for which no obvious explanation exists, usually are sampled by biopsy or aspiration.

Patient discussion about lymphadenopathy
Q. my friend ate a bar of chocolate and now her left neck gland is swollen any ideas why? no other symptoms
if it is an infection, you can usually find such other infection symptoms like : fever, pain in that swollen area, increased white blood cells (in blood work test), etc.
if it is an allergy, usually it will fade away itself in couple of days, or you can just try to consume anti-allergic drugs, such as : loratadine and maybe combined with dexamethasone.
Good luck, and stay healthy always..
