Swollen lymph nodes

Swollen lymph nodes mean that a lymph node — for example in the neck, armpit or groin — becomes enlarged and can be felt. Usually the swelling is due to the body’s immune system working, for example during a common cold or another respiratory infection. In that case, the lymph node may be tender, soft and movable. In children, swollen lymph nodes in the neck are almost always linked to benign infections and usually go away on their own.

In adults, swollen lymph nodes can also be caused by an infection, but sometimes there may be other reasons, such as medications or, more rarely, more serious illnesses. In general, swollen lymph nodes are not dangerous. You should be concerned if a swollen lymph node is painless, hard, grows quickly, does not shrink within a few weeks, or is accompanied by other symptoms such as night sweats, fever or weight loss.

If swollen lymph nodes persist for a long time or cause concern, it is a good idea to book an appointment with a healthcare professional. A professional can assess the situation and, if needed, refer you for further tests.
