Concussions in School Sports: When to Go to the ER
It is a scene a lot of families recognize. A kid takes a hard hit in football, bumps heads going for a soccer ball, or falls during cheer or basketball. They sit for a minute, look annoyed, and say, “I’m fine.”
Sometimes they are. Sometimes they are not.
A concussion is a type of brain injury caused by a bump, blow, or jolt to the head or body that affects how the brain works, and it does not always show up immediately. That is why knowing the true emergency warning signs matters.
What counts as a concussion (and why it can be hard to spot)
Concussion symptoms can show up right away, hours later, or even the next day. A student might seem mostly normal at first, then develop a headache, dizziness, nausea, or trouble concentrating later.
Also, a concussion usually will not “show up” on a CT or MRI the way a fracture does, which is why it is diagnosed based on symptoms and how the person is acting.
The simplest sports rule
If a concussion is suspected, the athlete should be taken out of play immediately and not return the same day. This is a core recommendation in CDC guidance for sports-related concussions.
Even if symptoms feel mild, playing through it raises the risk of a second injury while the brain is more vulnerable.
When to go to the ER right now
Here is the most important part of this article.
Go to the emergency department right away (or call 911) if any “danger signs” appear. Centers for Disease Control’s (CDC) HEADS UP program lists concussion danger signs that need emergency care.
Watch for these red flags, especially in the first 24 to 48 hours:
- A headache that gets worse and does not go away
- Repeated vomiting
- Seizure or convulsions
- Increasing drowsiness, can’t be woken up, or can’t stay awake
- Slurred speech, weakness, numbness, or decreased coordination
- One pupil larger than the other, or new double vision
- Unusual behavior, growing confusion, restlessness, or agitation
- Not recognizing people or places
Also treat it as urgent if the athlete is getting rapidly worse, seems “not themselves,” or you are simply scared by what you are seeing. You are not overreacting by choosing safety.
When it may not be the ER (but still needs attention)
Many concussions do not require an ER visit if there are no danger signs. But they still need to be taken seriously.
If symptoms are mild and stable, it is still wise to have the student checked as soon as possible (often same day or next day), and to keep them out of sports until they are cleared for a stepwise return.
Examples of “get checked soon” symptoms include headache, dizziness, nausea, feeling foggy, sensitivity to light or noise, and trouble concentrating, especially if these symptoms are new after a hit.
What to do in the first hours at home
Once the athlete is safely home (and you have ruled out emergency red flags), early care is mostly about rest, reducing symptom triggers, and watching for changes.
CDC guidance encourages rest as needed, but not staying in a dark room all day. It also suggests limiting screen time and other mentally or physically demanding activities for the first 1 to 2 days.
A few practical home steps:
- Keep things calm and quiet for the first day, with short breaks from screens.
- Offer water and simple meals if they feel up to it.
- Avoid rough play, risky activities, and anything that could lead to another head hit.
- Keep an adult nearby who can notice if symptoms worsen.
Should you wake them up every hour?
This is a common myth. CDC’s concussion Q and A says you can let a child or teen sleep uninterrupted after a concussion as long as they are not showing danger signs.
Pain medicine, what is safe?
Headaches are common after concussion. Different reputable sources give slightly different advice about ibuprofen early on.
- The American Academy of Pediatrics patient education says acetaminophen or ibuprofen can be used as needed for pain.
- Mayo Clinic advises acetaminophen and recommends avoiding ibuprofen and aspirin because they may increase bleeding risk.
If you are unsure what to use, acetaminophen is often the cautious first pick, and avoid aspirin. If symptoms are severe, worsening, or you are worried about bleeding risk, that is another reason to seek urgent evaluation.
When can they go back to sports?
Not the same day.
CDC lays out a stepwise return-to-play progression, where each step typically takes at least 24 hours, and symptoms must stay under control as activity increases.
If symptoms come back at any step, it is a sign to stop, rest, and step back.
Conclusion
Most school sports concussions recover well with the right care, but the key is catching the serious cases early and preventing a second hit too soon. If you see any danger signs like worsening headache, repeated vomiting, seizure, confusion, trouble waking, or weakness, go to the ER right away.
If there are no danger signs, take it seriously anyway: remove from play, rest for the first day or two, reduce screens, and follow a gradual return to school and sports.
FAQ
No. Many concussions can be managed without the ER if there are no danger signs. But anyone with danger signs should get emergency care right away.
Worsening headache, repeated vomiting, seizure, increasing drowsiness or inability to wake, confusion or unusual behavior, slurred speech, weakness or numbness, or one pupil larger than the other are major danger signs.
Yes, in many cases. CDC says you can let them sleep uninterrupted as long as they are not showing danger signs.
That can happen. Concussion symptoms can be delayed. If new symptoms appear after a hit, treat it seriously and get the student checked, especially if symptoms are worsening.
They should not return the same day. Return is typically a step-by-step progression that takes days, not hours, and symptoms should not worsen as activity increases.
Some pediatric guidance allows acetaminophen or ibuprofen, while other guidance recommends acetaminophen and avoiding ibuprofen early due to bleeding risk. If you are unsure, acetaminophen is often the cautious first choice, and seek urgent care if symptoms are severe or worsening.
