Sink traps: Lymph nodes are sink traps for our bodies. If you have infection or inflammation somewhere, your friendly hardworking lymph nodes will catch bits, work on it, & swell. They may feel tender. They may not hurt at all. Example: common cold & swollen neck lymph nodes. See your doc if you're concerned, if there's not an obvious neighborhood reason why your nodes are swollen, if it's more than 3-4 weeks.

Swollen nodes.: Nodes can swell because of infection or inflammation (some people refer to lymph nodes and tonsils as "glands") or because of local obstruction of their drainage (as in the salivary glands). So the best answer would depend on to which glands or nodes you are referring.

Not usually: Environmental and food allergies do not cause lymph node swelling. Generally lymph node swelling is associated with infections and less commonly with some cancers. However, there are some uncommon medication allergies that have lymph nodes swelling; one is called dress (drug reaction with eosinophilia and systemic symptoms).

Immune System HQ: The lymph nodes can be thought of as outposts for white blood cells. When there is an infection or inflammation in the area where a lymph node is draining fluid from, the white blood cells start to build up to fight it. This causes swelling in that node.
