So you bumped your head. Maybe it was a sports collision, maybe you slipped on ice, or perhaps that low doorway just jumped out at you. Now you're wondering: how to know if you got a concussion? Honestly, this happened to my nephew last fall during soccer practice. His coach brushed it off as "just getting his bell rung," but next morning he couldn't remember breakfast. Scary stuff.
The Sneaky Nature of Concussion Symptoms
Brain injuries don't always scream for attention like a broken bone. Symptoms can creep up hours or days later. I've seen people walk away from bike accidents feeling fine, then wake up vomiting at 3 AM. That's why learning how to know if you have a concussion is so crucial.
Physical Symptoms Checklist
Your body sends signals first. Watch for:
- Headache that won't quit (like a persistent drumbeat behind your eyes)
- Dizziness or balance issues (feeling like you just stepped off a merry-go-round)
- Nausea or vomiting (especially if it comes out of nowhere)
- Blurred vision or light sensitivity (sunlight suddenly feels like interrogation lamps)
- Ringing in ears (that annoying buzz that won't fade)
Cognitive & Emotional Red Flags
Here's where it gets tricky. These signs often get mistaken for fatigue or stress:
| Symptom | What It Feels Like | Danger Level |
|---|---|---|
| Brain fog | Thinking through molasses, forgetting why you walked into a room | Moderate |
| Confusion | Mixing up words, struggling with simple tasks like microwaving food | High |
| Mood swings | Unexplained rage or crying spells (my neighbor punched his fridge over spilled milk) | Moderate |
| Sleep disruption | Sleeping 14 hours or insomnia – both are red flags | High |
⚠️ EMERGENCY SYMPTOMS: Go to ER immediately if you experience:
- Uneven pupils
- Slurred speech
- Seizures
- Loss of consciousness (even briefly!)
The Concussion Timeline: When Symptoms Show Up
Timing matters. Some symptoms hit immediately, others play hide-and-seek:
| 0-4 hours post-injury | Headache, dizziness, nausea, blurred vision |
| 4-24 hours | Memory gaps, concentration issues, light/sound sensitivity |
| 24-72 hours | Sleep problems, emotional volatility, mental fatigue |
| 72+ hours | Persistent headaches, chronic dizziness (requires medical evaluation) |
A friend ignored his headache for two days after a ski fall, then couldn't recall his PIN at the grocery store. That's classic delayed onset.
The At-Home Concussion Check: What You Can Do Right Now
While nothing replaces professional evaluation, these quick checks help gauge severity:
- Balance test: Stand feet together, hands on hips, eyes closed. Can't hold for 30 seconds? Concern.
- Memory test: Recite months backwards starting from December. Stumbling? Take note.
- Eye tracking: Follow a finger moving horizontally without moving your head. Jerky motions signal trouble.
"Concussion diagnosis isn't about toughness. Pushing through symptoms can worsen outcomes."
- Dr. Alicia Torres, Neurologist at Boston Sports Medicine Clinic
Why Standard First Aid Protocols Fail
Most people think keeping someone awake after head trauma is critical. Actually, sleep helps healing – the danger lies in unmonitored sleep with escalating symptoms. If someone's napping after a bump:
- Check breathing every 30 minutes
- Wake them gently after 2 hours for symptom check
- Look for facial asymmetry before/after sleep
Medical Diagnosis: What Really Happens at the Clinic
Expect more than just a questionnaire. Standard concussion assessment includes:
- SCAT5 test: Standardized concussion tool evaluating balance, cognition, symptoms
- VOMS test: Measures eye focus changes after rapid head movements
- CT scans (only if skull fracture or bleeding is suspected)
Surprisingly, most concussions don't show on imaging. Diagnosis relies heavily on symptom patterns.
🚑 Bring a witness: ER doctors always ask "What happened right after impact?" Concussed patients often can't remember details.
The Recovery Reality: What They Don't Tell You
Recovery isn't linear. You'll have good days and setbacks. Key phases:
- Rest Phase (Days 1-3): Zero screens, no reading, quiet environment
- Light Activity Phase (Days 4-7): Short walks, limited screen time ≤20 mins/hour
- Moderate Activity Phase (Week 2): Gradual return to work/school with accommodations
Biggest mistake? Rushing back to screens. The blue light wrecks concussed brains. I learned this the hard way after trying to binge Netflix on day 3 – instant migraine.
Concussion FAQ: Real Questions People Actually Ask
Can I sleep after hitting my head?
Yes, unless emergency symptoms exist. Set alarms every 2 hours for symptom checks first night.
Do I need a CT scan?
Only if high-risk factors exist: vomiting over 3 times, worsening headache, age >65.
When should I worry about post-concussion syndrome?
If symptoms persist beyond 6 weeks, see a neurologist specializing in brain trauma.
Can painkillers help?
Avoid NSAIDs (ibuprofen, aspirin) first 48 hours – may increase bleeding risk. Tylenol only.
How to know if your concussion is healing?
Improving cognition during complex tasks, reduced headache frequency, returning emotional balance.
Concussion Prevention: Better Than a Cure
After seeing my nephew's ordeal, I became obsessive about prevention:
- In cars: Adjust headrests to ear level to prevent whiplash
- In sports: Replace helmets every 3 years or after any impact
- At home: Night lights in hallways (60% of concussions happen at home)
The Gear Truth: Helmets That Actually Protect
Not all helmets are equal. Look for:
| Activity | Certification Standard | Replacement Rule |
|---|---|---|
| Cycling | CPSC 1203 | After any crash or 5 years |
| Football | NOCSAE SEI certified | Every 2 seasons |
| Snow Sports | ASTM F2040 | After significant impact |
Cheap big-box store bike helmets? Often worse than nothing – they create false confidence.
When Returning to Normal Life Goes Wrong
Concussion management fails I've witnessed:
- A student returning to exams too soon, failing classes due to memory issues
- Construction workers hiding symptoms to keep working, leading to falls
- Gamers ignoring light sensitivity causing permanent visual disturbances
The hard truth: Trying to power through a concussion often adds weeks to recovery. Patience pays.
Why Kids Are Especially Vulnerable
Children's concussion symptoms differ dramatically:
| Symptom | Adults | Children |
|---|---|---|
| Headache | Localized pain | Whole-head complaints |
| Communication | Can describe issues | May become unusually quiet |
| Sleep Changes | Insomnia common | Excessive sleeping |
School accommodations are non-negotiable: half days, extended deadlines, no gym class.
Final Reality Check
Understanding how to know if you've gotten a concussion could prevent long-term complications. If you take away nothing else:
- Assume every significant head impact causes concussion until proven otherwise
- Document symptoms hourly for first 48 hours (phone notes work)
- Never hesitate to seek evaluation – ER bills beat brain damage
The moment you think "maybe I should get checked" – that's your sign to go. Trust me, I've regretted waiting. Your brain isn't something to gamble with.
