My son has knots on his neck. He just got over a fever, what could it be?

Hi Anonymous,

Swollen lymph nodes in the neck in children are very common due to infections that they can acquire. Do you know what his fever was for? Did he get seen by his doctor?

Although they are not contagious and can be seen when a viral or bacterial infection is present, please follow the following recommendations:

Call Your Doctor Now (night or day) If
Your child looks or acts very sick
Node in the neck causes difficulty with breathing, swallowing or drinking
Fever over 104° F (40° C) and not improved 2 hours after fever medicine
Overlying skin is red
Rapid increase in size of node over several hours

Call Your Doctor Within 24 Hours (between 9 am and 4 pm) If
You think your child needs to be seen
1 or more inches (2.5 cm or more) in size by measurement
Very tender to the touch
Interferes with moving the neck, arm or leg
Fever present for more than 3 days

Call Your Doctor During Weekday Office Hours If
You have other questions or concerns
In the neck and also has a sore throat
Large nodes at multiple locations
Cause of the swollen node is unknown
Age under 1 month old
Large node persists over 1 month

Best Wishes,

Rosa
