Lymphadenopathie
Swollen nodes usually mean the defence is working — hard, painless and growing ones need checking.

Lymph nodes are small filtering stations of the immune system. That they swell and become palpable — in the neck, armpits or groin — is usually a good sign: they are working, as a rule because of a nearby infection (a cold, a throat infection, an infected tooth, a skin injury). Such nodes are often tender, soft and movable and settle within days to a few weeks. Have nodes assessed that persist over several weeks or grow, that are hard, fixed and painless, that become larger than about 2 cm — or when accompanying signs like persistent fever, night sweats or unintended weight loss appear. The cause is usually harmless, but these patterns should be examined to be safe.
After an infection the nodes usually settle within days to weeks.
Constant prodding only irritates and makes them seem “busier”.
Persisting/growing, hard-fixed or with B-symptoms → have examined.
Treating the causing infection (e.g. a tooth) usually shrinks the node too.
A single, barely painful node on the neck with tiredness, often after raw meat or gardening, is a common and harmless first infection — the test is a blood test, not a biopsy.
The internal form causes fever, weight loss, a large spleen and swollen nodes over weeks. It comes from the Mediterranean region and the tropics and is treatable.
A lymph node counts as enlarged from about a centimetre. After an infection it needs two to four weeks to settle and can stay palpable as a small remnant for months — that is the normal case. Attention is due to nodes that keep growing beyond four to six weeks, are hard and fixed, measure over two centimetres, or sit above the collarbone.
An antibiotic works only if the node comes from a bacterial infection — that is not the case for most swollen nodes, and then it changes nothing. Cortisone is expressly not the route here: it shrinks the node and blurs exactly the picture needed for classification. What counts is time: watch for two to four weeks, and if it keeps growing, is hard and fixed, tissue is taken rather than treatment given.

Neck (cold/tooth), armpit/groin (skin/wound).
These features or growth over weeks → get assessed.
This combination should always be examined.
Fever, sweating and faster breathing clearly raise the need. Drinking enough keeps the mucus thin and the circulation steady — in children and older people it is the most important point of all.
With low levels airway infections occur somewhat more often; correcting a deficiency makes sense, a high single dose during the infection does not act on it.
Needed by the defence cells. For lozenges at the start of a cold there are hints of a slightly shortened duration; at a high dose over months zinc lowers copper.
Antibodies and defence cells are protein. After several days with little appetite it is worth at least keeping the protein up — soup with egg, quark, yoghurt, lentils.
Taken continuously it shortens colds by about half a day. It does not act on a swollen node — that recedes with the infection, over 2–4 weeks.
The studies have contradicted each other for decades; large well-made trials found no difference. A node that stays beyond 4 weeks, hardens or grows belongs looked at rather than treated.
Clearly worthwhile and well studied when deficient; fewer data for the wider uses. Fat-soluble — check blood levels at high doses.
Not every lump in the neck is a lymph node. A lump that moves upward when swallowing belongs to the thyroid — that one manoeuvre separates two completely different work-ups.
Cortisone makes swollen lymph nodes shrink — including those of a lymphoma. This is why it belongs here only after the biopsy, not before: it blurs exactly the picture that is needed.
Swollen lymph nodes belong assessed by their cause, not by the menu. If they last over 3–4 weeks and grow, that belongs looked at — time is what matters here.
Used to strengthen defences; the studies are inconsistent. Time matters more here: nodes that stay over 3–4 weeks, grow, or are hard and fixed belong looked at.
