Lymph nodes help the body fight infection. There are lymph nodes in many parts of the body, including the neck. If a virus enters the body through the nose or mouth, it may travel to lymph nodes in the neck. This causes the neck lymph nodes to swell. This is called viral cervical adenitis. It's common in children.
Symptoms of viral cervical adenitis include a swollen neck. It may be painful to the touch. The skin may be warm and red. Your child may have a fever. They may be fussy and not want to eat. Your child may have recently had a cold, sore throat, or earache.
Children with viral cervical adenitis may be treated for pain and fever. Viral cervical adenitis will usually go away in a few days to weeks.
Cervical adenitis can also be caused by bacteria or things that aren't infections.
Home care
Your child may be given medicine for pain and fever. Follow all instructions for giving these medicines to your child. Don’t give aspirin or any product with aspirin in it to a child younger than age 19. Aspirin use in children younger than 19 has been linked to a serious condition called Reye syndrome.
General care
-
Allow your child plenty of time to rest. Plan quiet activities for a few days.
-
Make sure that your child drinks plenty of fluids. Contact your child’s health care provider if your child refuses to eat or drink, or urinates less often than normal.
-
Check your child’s lymph nodes for changes in size. Your child's provider may draw around the lymph nodes with a marker to help you see if the swelling changes over time.
-
To help ease discomfort, you can apply a cold or warm compress to the painful area for about 15 minutes.
Follow-up care
Follow up with your child’s health care provider as advised.

-
Fever of 100.4°F (38°C) or higher, or as directed by the provider
-
Chills

Refusal to eat or drink

Lymph glands that are swollen and tender for more than 5 days

Fever and children
Use a digital thermometer to check your child’s temperature. Don’t use a mercury thermometer. There are different kinds and uses of digital thermometers. They include:
-
Rectal. For children younger than 3 years, a rectal temperature is the most accurate.
-
Forehead (temporal). This works for children age 3 months and older. If a child under 3 months old has signs of illness, this can be used for a first pass. The health care provider may want to confirm with a rectal temperature.
-
Ear (tympanic). Ear temperatures are accurate after 6 months of age, but not before.
-
Armpit (axillary). This is the least reliable but may be used for a first pass to check a child of any age with signs of illness. The provider may want to confirm with a rectal temperature.
-
Mouth (oral). Don’t use a thermometer in your child’s mouth until they are at least 4 years old.
Use the rectal thermometer with care. Follow the product maker’s directions for correct use. Insert it gently. Label it and make sure it’s not used in the mouth. It may pass on germs from the stool. If you don’t feel okay using a rectal thermometer, ask the provider what type to use instead. When you talk with any provider about your child’s fever, tell them which type you used.
Below are guidelines to know if your young child has a fever. Your child’s provider may give you different numbers for your child. Follow your provider’s specific instructions.
