What is Swollen glands?
Swollen glands, or lymph nodes, are a common sign that your immune system is actively fighting an infection. They're most often felt in the neck, armpits, or groin, and typically feel like small, tender lumps under the skin.
Most swollen glands are caused by common infections such as colds, sore throats, or ear infections, and settle down within a couple of weeks as the infection clears. Persistent, painless, or widespread swelling occasionally needs further investigation.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Rest and stay hydrated.This supports your body's immune response to the underlying infection.
- 2Take pain relief if needed.Paracetamol or ibuprofen can ease any discomfort from tender glands.
- 3Apply a warm compress if uncomfortable.Gentle warmth can help ease tenderness in some cases.
- 4Monitor how the swelling changes.Most swollen glands linked to an infection will start reducing in size within one to two weeks.
- 5Avoid squeezing or pressing on glands repeatedly.This won't speed healing and can cause unnecessary discomfort.

BarnMD Bottom Line
Swollen glands are usually a reassuring sign that your immune system is working, and most settle within a couple of weeks as an infection clears.
Glands that are hard, painless, and steadily growing — rather than tender and linked to an obvious infection — are the pattern that needs checking.
