Head injuries are common — from sports, falls, and car accidents — and most minor bumps heal on their own. But some head injuries are serious and can worsen over hours. Knowing the warning signs you should never ignore can help you get life-saving care in time. This guide explains which head injury symptoms mean you should go to the ER.
Why Head Injuries Deserve Attention
The brain is protected by the skull, but a hard blow can still cause bruising, bleeding, or swelling inside — sometimes with a delay. A person can seem fine right after a head injury and then deteriorate. That’s why certain warning signs should always be taken seriously, even if the injury seemed minor at first.
Head Injury Symptoms You Should Not Ignore
Go to the ER right away — or call 911 for severe symptoms — if a head injury is followed by any of these:
- Loss of consciousness, even briefly
- Repeated vomiting
- A severe or worsening headache
- Confusion, disorientation, or unusual behavior
- Slurred speech
- Weakness, numbness, or trouble with coordination
- A seizure
- Unequal pupil sizes
- Clear fluid or blood draining from the nose or ears
- Unusual drowsiness or difficulty waking
- Vision changes
Understanding Concussions
A concussion is a mild traumatic brain injury caused by a blow or jolt to the head. Symptoms include headache, dizziness, confusion, sensitivity to light or noise, nausea, and “feeling foggy.” While most concussions improve with rest, they still deserve evaluation — especially in children, athletes, and anyone whose symptoms worsen.
Head Injuries in Children
Children are especially prone to falls and head bumps. Seek emergency care if a child loses consciousness, vomits repeatedly, is unusually sleepy or irritable, won’t stop crying, has a bulging soft spot (in babies), or seems “not themselves” after a head injury.
Head Injuries and Blood Thinners
If you take blood-thinning medication, even a minor head injury carries a higher risk of bleeding inside the skull. Anyone on blood thinners should be evaluated after a head injury — don’t wait for symptoms to appear.
When It May Be Minor
A small bump with no loss of consciousness, normal alertness, and no worsening symptoms may be watched at home — but keep an eye out for any of the warning signs above over the next 24–48 hours, and seek care if they develop.

Frequently Asked Questions
What are the warning signs of a serious head injury?
Loss of consciousness, repeated vomiting, worsening headache, confusion, slurred speech, weakness or numbness, seizure, unequal pupils, fluid from the nose or ears, or unusual drowsiness. Any of these means go to the ER — call 911 for severe symptoms.
When should I go to the ER for a head injury?
Go right away if there was loss of consciousness, repeated vomiting, worsening headache, confusion, or any neurological symptom — or if the injured person takes blood thinners. When in doubt, get evaluated.
Can a head injury get worse hours later?
Yes. Bleeding or swelling inside the skull can develop with a delay, so someone may seem fine at first and worsen over hours. Watch closely for 24–48 hours and seek care if warning signs appear.
Do I need a CT scan for a head injury?
If your symptoms suggest possible bleeding, yes — a CT scan is the fastest way to check. Eastex Emergency Room has an on-site CT scanner with fast results, 24/7.
When should I worry about my child’s head injury?
Seek emergency care if your child lost consciousness, vomits repeatedly, is unusually sleepy or irritable, has a bulging soft spot, or seems “not themselves” after hitting their head.
