Swollen lymph nodes in the neck, armpit and groin: what lymph nodes do, why they swell, how long is normal, when to seek care, and what you can do (and not do) with lymphatic massage and cupping

You feel a tender lump in the neck, under the jaw or in the armpit, and the first thing you think is the worst. In reality, swollen lymph nodes are almost always a sign that the immune system is doing its job: the nodes are filter stations where white blood cells meet bacteria and viruses from the throat, teeth, skin or a nearby wound, and they grow while they work. Here we explain where the lymph nodes sit and what they do, the common causes (colds, strep throat, dental infection, glandular fever, wounds and eczema), how a harmless node feels compared with one that should be examined (hard, fixed, painless, growing, larger than 2 cm, above the collarbone, with night sweats and weight loss), how long it is normal for them to be swollen, and what you can do yourself: rest, fluids, warmth during infection, light lymphatic massage of the healthy surroundings to help drainage once the acute phase is over, and why you should never press on, massage or cup over the swollen node itself.

The lymphatic system: how it works – lymph, lymph vessels, lymph nodes and what they do, why it gets sluggish, swollen lymph nodes, and how to keep lymph moving with breathing, movement and cupping

The lymphatic system is the body's second circulation: a network of vessels and nodes that collects the fluid, proteins, fats and waste that leak out of the blood vessels, filters it through the lymph nodes where the immune system works, and returns it to the blood. It has no pump of its own but is driven by breathing, muscle work and the vessels' own contractions, which is why sitting still, shallow breathing and stress make lymph move slowly. Here is how the system is built, where the lymph nodes are and why they swell, what happens when the flow gets sluggish (swelling, heaviness, lymphoedema), what is true and false about 'lymph cleansing', and how to keep lymph moving with breathing, movement, water, lymphatic massage and cupping.
