Concussion Symptoms in Children: What to Watch After a Head Injury
Concussion symptoms in children typically include headache, dizziness, confusion, nausea, and sensitivity to light or noise, and they can appear immediately or develop over several hours after a head injury.
A concussion is a mild traumatic brain injury caused by a bump or jolt to the head. It does not require a loss of consciousness to be serious, and children do not always complain of head pain afterward, which is what makes it easy to miss.
Other common concussion symptoms in children include a feeling of pressure in the head, a slowed or foggy response to questions, balance problems, vomiting, and irritability or emotional changes that seem out of proportion to the situation.
Concussion symptoms in children do not always appear immediately. Monitor your child for at least four to six hours after any significant head impact, even if they seem fine right after the fall. Individual children can present differently, and only a medical evaluation can confirm a concussion diagnosis.
Signs of Concussion in a Toddler
Toddlers and younger children cannot describe how they feel, which makes recognizing a concussion harder. Watch for inconsolable crying after a head bump, vomiting more than once, unusual sleepiness or difficulty staying awake, glassy or unfocused eyes, and loss of coordination or balance that was not present before the fall. If your toddler took a significant head impact and is showing any of those signs, same-day evaluation is the right call.
Return to School and Return to Play After a Concussion
Recovery from a concussion is not just about symptoms resolving. Most children need a structured return-to-school and return-to-play protocol before resuming full academic and athletic activity. Returning too soon, before the brain has adequately recovered, can slow healing and increase the risk of a second concussion while the first is still healing.
A typical return-to-play protocol moves through gradual stages, starting with rest, then light aerobic activity, then sport-specific exercise, before full contact practice and competition are cleared. Return-to-school follow-up is similar, often starting with reduced screen time and shortened school days before a full schedule resumes. Both timelines vary depending on the child’s age and how their symptoms progress.
Your child’s primary care provider should clear them before returning to contact sports or full practice.
If you are looking for that follow-up care after a concussion evaluation at PUCNC, The Youth Clinic handles sports clearance and shares records with our team so nothing falls through the gap. Request an appointment at The Youth Clinic.
What’s the Difference Between a Strain, Sprain or Break?
Once a head injury has been assessed or ruled out, the next question is usually what happened to the limb? Pain, swelling, and bruising appear across all three injury types below, which is why they are easy to confuse at home and why a proper evaluation matters.
Is It Broken or Sprained?
Sprains and fractures share enough symptoms that you genuinely may not be able to tell the difference at home, and that is a reasonable reason to come in.
- A sprain typically allows some movement of the joint despite pain and swelling
- A fracture is more likely when your child cannot bear weight on the limb, when there is visible deformity, or when the pain is severe and worsening rather than stabilizing after the first several minutes
In children, growth plate injuries can feel and look identical to a sprain, which is why an X-ray is the only reliable way to confirm what you are dealing with.
Strains
- Strains affect muscles and tendons and can happen when muscles or tendons are overstretched or overused
- Common symptoms include pain and tenderness, redness or bruising, limited movement, muscle spasm, swelling, and muscle weakness
Sprains
- Sprains occur when ligaments supporting joints are overstretched or torn. In severe cases, ligaments are completely torn and no longer able to support the joint properly
- Common symptoms include pain, swelling, bruising, restricted joint movement, and a popping sound during injury
Breaks
- Breaks occur when the bone has been shattered or fractured. Immediate medical attention is necessary
- Symptoms include sudden pain, difficulty moving the area, inability to bear weight, swelling, warmth, bruising, redness, and visible deformity
When to Seek Medical Treatment
Consult a healthcare provider if your child experiences immediate pain after an accident, pain that disrupts their sleep, persistent pain, or reluctance to use the injured body part.
For younger children, falls from playground equipment, monkey bars, and climbing structures are among the most common causes of the injuries above. When a child reaches out to break a fall, the force typically travels to the wrist and forearm, making those the most frequent fracture sites in children. Ankle sprains from awkward landings and head injuries from falls onto hard surfaces are also common during active outdoor play. If the injury happened from a fall greater than your child’s own height, or your child will not bear weight on a limb, same-day evaluation is the right call.
For older kids and high schoolers, sports are a more common setting. Ankle and knee sprains from cutting and pivoting in soccer, basketball, and football, wrist and collarbone fractures from contact sports and wrestling, and concussions from collisions in any contact or collision sport all warrant same-day evaluation. Older athletes often push through pain, so reluctance to return to play or a noticeable change in performance after a hit can be just as telling as visible swelling or a complaint of pain.
Why Pediatric Assessment Is Different for Every Injury Type
Whether the injury is a suspected concussion or a possible fracture, children are not simply smaller adults and their injuries should not be treated that way. Children’s bones are softer and actively growing, which means fractures can involve the growth plates in ways that require specific evaluation. Growth plate injuries can look and feel identical to a sprain and will not always show obvious deformity. Concussions in children also present differently than they do in adults, and a pediatric-trained provider will approach both assessments with that in mind.
Pediatric Urgent Care of Northern Colorado has on-site X-ray, pediatric-trained providers, and is open 365 days a year including weekends and holidays. View our live waitlist before you come in. For more on how we treat fractures, visit our broken bones and dislocations page. For sprains and strains, visit our sprains and strains page. For ongoing recovery, sports clearance, or follow-up care after any of the injuries covered here, The Youth Clinic is our primary care partner and shares records with our team so care continues without starting over. Review our comprehensive care options to understand how both practices work together.
When to Go to Urgent Care vs. the Emergency Room
For sprains, strains, fractures, and suspected concussions without severe symptoms, Pediatric Urgent Care of Northern Colorado is the right choice. Urgent care is typically faster and less costly than an emergency room for injuries that are serious but not life-threatening.
Go to an emergency room or call 911 if your child loses consciousness even briefly, has a seizure, cannot be woken up, has one pupil visibly larger than the other, has fluid draining from the nose or ears, or has a bone visibly breaking through the skin. Those are signs that require emergency level care.
If the injury happened on a weekend, holiday, or after your pediatrician’s office has closed, we are open every day of the year. Check our current hours and location before you come in.
Frequently Asked Questions
Q: What are the most common concussion symptoms in children after a fall?
Concussion symptoms in children typically include headache, confusion, dizziness, nausea, sensitivity to light or noise, and unusual irritability. Toddlers may show inconsolable crying, vomiting, or unusual sleepiness. Symptoms can appear immediately or develop over several hours. Individual children can present differently, and only a medical evaluation can confirm a concussion diagnosis.
Q: How can I tell if my child's injury is a sprain or a fracture?
Both cause pain, swelling, and bruising, making them difficult to distinguish without imaging. A fracture is more likely if your child cannot bear weight, has visible deformity, or has severe worsening pain. In children, growth plate injuries can feel identical to a sprain. An X-ray is the only reliable way to confirm.
Q: When should I take my child to urgent care versus the ER after a head injury?
Go to an ER or call 911 for loss of consciousness, seizure, unequal pupils, or fluid from the nose or ears. Suspected concussion without those signs is appropriate for pediatric urgent care, which is typically faster and less costly for non-life-threatening head injuries.
Q: When can my child return to sports after a concussion?
Children should follow a gradual return-to-play protocol supervised by a healthcare provider before returning to contact sports or full practice. Returning too soon increases the risk of a second concussion while the brain is still healing. A primary care provider should provide formal clearance. Individual timelines vary depending on the child’s age and symptom progression.
