Why Does My Child Have a Lump in Their Neck? A Parent’s Guide to Swollen Glands
Discovering a lump in your child’s neck can be unsettling.
You may notice it while washing their hair, fastening a school shirt or cuddling them at bedtime. Sometimes your child finds it first and says there is a small “ball” under the skin.
One of the first questions parents understandably ask is:
“Should I be worried?”
Fortunately, the majority of neck lumps in children have a benign explanation, and swollen lymph nodes associated with infections are particularly common. NICE states that reactive cervical lymphadenopathy is the most likely cause of a neck lump in children.
However, not every neck lump is simply a swollen gland. Its position, size, duration, whether it is painful and whether your child has other symptoms all matter.
This guide explains common causes, what parents can monitor and when medical or paediatric ENT assessment is appropriate.
What are the little glands in my child’s neck?
The “glands” parents can feel in the neck are usually lymph nodes.
Lymph nodes form part of the immune system. They filter lymphatic fluid and help the body respond to infections.
There are groups of lymph nodes throughout the body, including:
- beneath the jaw
- along both sides of the neck
- behind the ears
- at the back of the head
- in the armpits
- in the groin.
When a child develops an infection nearby, these lymph nodes may become more active and enlarge.
NHS guidance explains that swollen glands are commonly a sign that the body is fighting infection and may occur alongside sore throat, cough or fever.
Why can I feel lymph nodes more easily in children?
Children are constantly encountering new viruses and infections.
Their lymphatic system is therefore frequently active.
They also have relatively small necks and less tissue covering the lymph nodes than many adults, which can make small nodes easier to feel.
Kingston and Richmond NHS notes that lymphadenopathy is very common in children and is frequently a normal reactive response to illnesses such as colds or tonsillitis.
A small movable node after a recent cold is therefore a very different situation from a rapidly enlarging unexplained neck mass.
Can a cold cause a lump in the neck?
Yes.
Upper respiratory infections are among the commonest reasons for lymph nodes in a child’s neck to enlarge.
This includes:
- ordinary viral colds
- sore throats
- tonsillitis
- some ear infections
- other viral illnesses.
When the infection settles, the lymph node usually starts becoming smaller.
NHS advice says that infection-related swollen glands generally improve within 1 to 2 weeks, although small lymph nodes can remain palpable for longer.
Do not repeatedly squeeze or measure the lump throughout the day. Frequent touching can make the area feel more noticeable and can increase parental anxiety without providing useful information.
Can tonsillitis cause swollen neck glands?
Yes.
The tonsils and neck lymph nodes are closely connected through the lymphatic system.
A child with tonsillitis may have:
- sore throat
- pain when swallowing
- fever
- enlarged or inflamed tonsils
- white patches on the tonsils
- painful lymph nodes in the neck.
NHS guidance on tonsillitis specifically lists swollen, painful neck glands among possible symptoms.
These nodes normally improve as the throat infection resolves.
What does an infected lymph node look like?
Occasionally a lymph node itself becomes significantly inflamed or infected. This is called lymphadenitis.
The lump may become:
- increasingly painful
- tender
- larger
- warm
- associated with redness of the skin
- accompanied by fever.
ENT UK has dedicated guidance for children presenting to hospital with lymphadenitis or a lymph node abscess, reflecting that a significantly inflamed node occasionally requires more than simple observation.
A child with a rapidly enlarging painful neck swelling, fever or overlying redness should therefore be medically assessed.
Could eczema make lymph nodes larger?
Yes.
Children with significant eczema may have palpable reactive lymph nodes due to ongoing skin inflammation.
NHS paediatric guidance notes that eczema can be associated with enlarged lymph nodes, which may improve when the underlying skin inflammation is controlled.
Again, the whole clinical picture matters.
What if the lump is in the middle of the neck?
A lump in the centre of the neck may be different from an ordinary reactive lymph node.
One childhood possibility is a thyroglossal duct cyst.
ENT UK describes a thyroglossal duct cyst as a benign fluid-filled lump that commonly becomes noticeable during childhood. It often appears as a small, round swelling towards the front or middle of the neck and can occasionally become infected during illnesses such as a cold.
One classic feature is that the lump may move when the child swallows or sticks out their tongue.
An ultrasound scan can often help assess this type of lump.
Parents should not try to decide from this feature alone whether a lump is a cyst. A persistent midline neck lump deserves examination.
What other congenital neck lumps occur in children?
Some children are born with developmental remnants that become noticeable only later.
These can include:
- thyroglossal duct cysts
- branchial cysts
- other less common congenital swellings.
They may become more obvious during or after an infection because inflammation causes them to enlarge.
NICE advises ENT referral where a branchial or thyroglossal cyst is suspected.
This is one reason the location of a neck lump is important.
Does every child with a neck lump need antibiotics?
No.
Antibiotics do not treat reactive lymph nodes from viral infections.
Paediatric NHS guidance notes that antibiotics are not normally required for uncomplicated swollen lymph nodes; bacterial infection becomes more likely when a node is particularly painful, inflamed or associated with features such as fever and local redness.
Treatment should therefore be based on examination rather than the presence of a lump alone.
Does my child need an ultrasound?
Not every small lymph node needs scanning.
Ultrasound becomes useful when the diagnosis is unclear or the clinician wants more information about:
- the size and structure of a lump
- whether it is a lymph node or cyst
- whether fluid or an abscess is present
- its relationship to surrounding structures.
ENT UK describes ultrasound as particularly useful when investigating areas of the neck including lymph nodes and other soft tissues.
An ultrasound does not automatically mean that something serious is suspected. It is simply one tool for clarifying what the swelling represents.
How long should I watch a swollen gland?
There is no single number that applies to every child.
A small mobile node, even after a clear infection, can persist for some time, even after the child is well.
What matters is the trend.
Reassuring features include a lump that:
- appeared with a cold or sore throat
- is small
- is movable beneath the skin
- gradually becomes smaller
- is accompanied by otherwise normal health.
NICE advises further assessment when lymphadenopathy persists or progressively enlarges rather than resolving as expected.
Persistent lumps should therefore not simply be ignored indefinitely.
When should parents arrange a GP or ENT assessment?
Arrange medical review if:
- the lump continues to enlarge
- it remains persistently enlarged
- there was no obvious preceding infection
- it feels unusually hard or fixed
- there is a persistent single unexplained neck lump
- the skin becomes red or hot
- the child has prolonged fever
- a midline neck cyst is suspected
- the lump repeatedly becomes infected.
NICE specifically highlights persistent or rapidly growing neck masses as findings that require careful assessment.
What symptoms should make parents more concerned?
A neck lump deserves more prompt investigation when accompanied by symptoms such as:
- unexplained weight loss
- drenching night sweats
- persistent unexplained fever
- unusual bruising
- marked tiredness or pallor
- lumps developing in several areas of the body
- progressive enlargement.
These findings remain uncommon, but they are important reasons to seek medical assessment rather than assuming every lump is simply reactive.
Current NHS paediatric guidance advises review for features such as rapidly enlarging lymph nodes, persistently enlarged nodes, unexplained bruising, or weight loss.
The presence of one of these symptoms does not automatically mean cancer. It means the child needs appropriate clinical assessment.
Red flags: when is a neck swelling urgent?
Seek urgent medical advice if a child has a neck swelling together with:
- difficulty breathing
- significant difficulty swallowing
- drooling or inability to swallow saliva
- rapidly increasing swelling
- severe neck pain or stiffness
- marked redness with high fever
- significant lethargy or appearing seriously unwell.
NHS guidance recommends urgent help for significant breathing or swallowing difficulty associated with swollen glands or severe throat illness.
Call 999 if the child is struggling significantly to breathe, becomes blue or grey, collapses or is difficult to wake.
When should a child see a paediatric ENT specialist?
Paediatric ENT assessment may be useful when:
- a neck lump persists
- the lump is progressively enlarging
- lymphadenitis is recurrent
- an abscess is suspected
- a thyroglossal or branchial cyst is possible
- an ultrasound requires specialist interpretation
- the diagnosis remains unclear
- surgery may eventually need consideration.
Assessment may include examination of the ears, nose, mouth, and throat because infections in these areas frequently explain neck node enlargement.
Depending on the findings, an ultrasound, blood tests or further investigations may be recommended.
Paediatric neck-lump assessment in London and Essex
Finding a lump in your child’s neck understandably creates anxiety, but most childhood neck lumps are benign, with reactive lymph nodes following common infections being particularly frequent.
Mr Gaurav Kumar, Consultant ENT Surgeon, assesses children with persistent neck lumps, recurrent lymph-node infections, thyroglossal cysts, tonsil and throat problems and other paediatric ENT concerns from London, East London, Romford, Ilford, Redbridge, Brentwood, Chelmsford and surrounding areas of Essex.
The aim of assessment is to establish what the lump represents and whether anything further is required, rather than assuming that every palpable lymph node needs scans or treatment.
The key message for parents
Small neck glands are very common in children, particularly during and after colds, sore throats and tonsillitis.
A small mobile node that appeared during an infection and gradually becomes smaller is usually reassuring.
However, arrange assessment if a lump keeps enlarging, remains significantly enlarged, becomes red and painful, has no clear explanation or is accompanied by persistent fever, weight loss, night sweats, unusual bruising or other concerning symptoms.
And if a neck swelling is interfering with your child’s breathing or swallowing, seek urgent medical help.
Frequently asked questions
Are swollen neck glands common in children?
Yes. Reactive lymph nodes are very common during childhood, particularly around respiratory and throat infections. NICE identifies benign reactive lymphadenopathy as the commonest cause of childhood neck lumps.
How long does a swollen gland last after a cold?
Infection-related swelling often improves over one to two weeks, although small palpable nodes may remain noticeable longer.
Can tonsillitis cause a lump in the neck?
Yes. Tender swollen neck lymph nodes are a recognised symptom of tonsillitis.
Should I keep checking the lump every day?
It is sensible to notice whether it is clearly growing or shrinking, but repeatedly squeezing or manipulating the node is unnecessary.
Does every neck lump need an ultrasound?
No. Ultrasound is usually considered when the diagnosis is uncertain, the lump persists or its characteristics warrant further assessment.
What is a lump in the middle of my child’s neck?
One possibility is a thyroglossal duct cyst, particularly if it moves when swallowing or sticking out the tongue. It should be clinically assessed rather than diagnosed at home.
When should I worry about swollen glands?
Seek assessment for progressively enlarging or persistent lumps, unexplained fever, weight loss, drenching night sweats, unusual bruising or a child who appears unwell.
When is a neck lump an emergency?
Rapid swelling associated with significant breathing difficulty, inability to swallow, severe illness or collapse requires urgent/emergency help.
