When a child has a headache with fever

A fever and headache in a child often happen together during common illnesses such as viral infections, flu, colds, strep throat, sinus infections, or ear infections. In some cases, dehydration, poor fluid intake, or body aches from being sick can also make a headache worse. Most children improve with rest, fluids, and close monitoring, but the pattern of symptoms matters. A severe headache, vomiting, unusual sleepiness, neck stiffness, trouble breathing, confusion, or a child who seems much worse than expected can mean it is time to seek urgent medical care.

Common causes of headache and fever in kids

Viral illness

Many children get headache and fever from a routine viral infection. This may come with tiredness, sore throat, cough, congestion, or body aches.

Flu, strep, or sinus infection

A child headache with fever may also happen with influenza, strep throat, or a sinus infection, especially if there is facial pressure, sore throat, or worsening symptoms after several days.

Dehydration or not drinking enough

When kids have fever, they can lose fluids quickly. Less drinking, vomiting, or poor appetite can lead to dehydration, which may make a headache stronger.

When to worry about headache and fever in a child

The headache seems severe or unusual

If your child says the pain is very strong, cries from the pain, cannot do normal activities, or the headache feels different from past headaches, it deserves prompt attention.

There are other concerning symptoms

Headache with fever in a child plus vomiting, neck stiffness, confusion, trouble waking up, weakness, a seizure, or a rash should be evaluated urgently.

Symptoms are lasting or returning

If headache and fever have lasted more than a day or keep coming back, it may be time to look more closely at the cause and whether your child should be seen.

What information helps guide next steps

Your child’s age

A fever headache in a toddler may be assessed differently than the same symptoms in an older child, especially if they cannot describe the pain clearly.

How long symptoms have been present

Whether the headache and fever started today, have lasted more than a day, or keep coming back can change what is most likely and what to do next.

Other symptoms happening at the same time

Vomiting, sore throat, cough, congestion, ear pain, stomach pain, rash, or low fluid intake can all help explain what causes headache and fever in children.

Frequently Asked Questions

What causes headache and fever in children?

Common causes include viral infections, flu, colds, strep throat, sinus infections, ear infections, and dehydration. The most likely cause depends on your child’s age, how long symptoms have lasted, and whether there are other symptoms like vomiting, sore throat, or congestion.

When should I worry about headache and fever in my child?

You should seek urgent care if your child has a severe headache, repeated vomiting, neck stiffness, confusion, trouble waking up, trouble breathing, a seizure, weakness, or seems much sicker than expected. If symptoms are not urgent but last more than a day or keep returning, medical guidance is still a good idea.

Is headache and fever in kids usually serious?

Often, no. Many cases are linked to common infections and improve with time, fluids, and rest. Still, some patterns need closer attention, especially if the headache is severe, your child is not acting like themselves, or there are additional warning signs.

What if my child has a headache with fever and vomiting?

Vomiting can happen with fever, pain, dehydration, or some infections, but it can also be a warning sign when it happens with a strong headache. If your child has repeated vomiting, cannot keep fluids down, seems very sleepy, has neck stiffness, or the headache is severe, seek urgent medical care.
