Swollen lymph nodes, often called swollen glands, are common in children and usually reflect the immune system responding to a nearby cold, sore throat, ear infection, dental problem, or skin irritation. Most are not dangerous and shrink slowly after the illness improves.

Urgent Warning Signs - Check This First

A lump in the neck should not be squeezed, repeatedly pressed, or treated with leftover antibiotics. Urgency depends on breathing, swallowing, illness severity, rapid change, and the child's overall appearance.

CALL 911 NOW

  • Trouble breathing, noisy breathing, blue or gray color, severe drooling, or inability to swallow saliva

  • Rapidly worsening neck swelling with severe breathing difficulty, a child who is unresponsive, or another life-threatening emergency

GET EMERGENCY MEDICAL CARE NOW

  • A rapidly enlarging, red, hot, very painful neck lump with fever, severe neck stiffness, or a child who looks very ill

  • Neck swelling with inability to drink, significant dehydration, muffled voice, trouble opening the mouth, or worsening swallowing difficulty

  • Fever with severe headache, stiff neck, confusion, persistent vomiting, or light sensitivity

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • A node or neck lump that is rapidly growing, red or purple over the skin, warm, very tender, or associated with fever

  • A hard, fixed, or nonmovable lump; a lump above the collarbone; or enlarged nodes in several areas of the body

  • A swollen node with unexplained weight loss, night sweats, easy bruising or bleeding, unusual fatigue, poor appetite, or ongoing fever

  • A painful node that has not begun to improve within several days, or a node that persists or remains enlarged beyond about 4 weeks

  • A new unexplained neck mass, a lump after animal exposure or travel, or a child with an immune condition or a concerning medical history

What Can Be Normal

  • Small, movable, mildly tender nodes under the jaw or along the neck during or after a cold, sore throat, ear infection, dental inflammation, or scalp irritation

  • Nodes that become noticeable during illness and then shrink gradually over several weeks. They may not disappear immediately.

  • Children, especially younger children, often have more easily felt nodes because their immune systems are frequently responding to new infections.

When a Lymph Node May Be Infected

A lymph node can occasionally become infected itself. This may cause a more rapidly enlarging, red, warm, painful lump and fever. A clinician may need to examine the child, look for a nearby infection, and decide whether tests, antibiotics, imaging, or drainage are needed.

What Families Can Do

  • Treat the child's cold, sore throat, ear, dental, scalp, or skin symptoms only as previously advised by a clinician. Do not give leftover antibiotics.

  • Avoid repeatedly checking or pressing the node; this can make it sore and makes change harder to judge.

  • Note the location, approximate size, pain, overlying skin changes, fever, other symptoms, recent illnesses, animal contact, and travel.

  • Use a photograph only if it helps document visible swelling. A photograph cannot determine whether a lump is a lymph node or its cause.

What a Clinician May Do

The clinician may examine the neck, ears, nose, throat, mouth, skin, and other lymph-node areas. They may ask about illness, dental problems, pets, travel, medicines, and family history. Persistent or concerning lumps may need blood work, ultrasound, referral, or other testing to identify the cause.

Call Preparation

  • Location and timing of the lump; whether it is changing, painful, red, warm, firm, or movable

  • Recent cold, sore throat, ear pain, dental symptoms, skin rash or wound, fever, night sweats, appetite or weight change, and fatigue

  • Animal exposure, tick bites, travel, medications, immune conditions, and prior similar episodes

  • Any breathing, swallowing, drinking, voice, or neck-movement difficulty
