# Sports-Related Injuries in Teens & Adolescents
### TeenThreads Real-Talk Guide to “Is This a Small Injury… or a ‘Stop Playing Right Now’ Injury?”
## Why TeenThreads Is Talking About This
Sports are a glow-up for your body and brain… but injuries can turn “best season ever” into “why does my knee hate me.” The biggest trap teens fall into is **playing through pain** (because pressure, tryouts, scholarships, coach vibes, or just pride).
TeenThreads goal:
👉 Help you know **what’s common**, **what’s serious**, how to **treat early**, and how to **return safely** (especially after concussion). No drama. Just smart.

## What Are Sports-Related Injuries? (Simple + Real)
A sports injury is any damage to muscles, bones, ligaments, tendons, joints, or the brain that happens during:
* practice
* games
* gym class
* training
* “messing around” (yes, that counts)
Two big buckets:
* **Acute injuries** = sudden (sprain, fracture, concussion)
* **Overuse injuries** = build up over time (tendinitis, stress fractures)
NIAMS lists common sports injury types like fractures, dislocations, sprains, strains, tendinitis, and bursitis. ([NIAMS][1])
Other Name(s)
* Athletic injuries
* Sports trauma
* Overuse injuries / repetitive stress injuries
* Concussion / mild traumatic brain injury (mTBI)
Difference Between Normal Soreness vs Injury
Normal soreness (DOMS)
* starts 12–24 hours after a hard workout
* feels like “tight and sore,” not sharp
* improves in a few days
Injury signals
sharp pain, popping, or sudden “snap”
* swelling or bruising quickly
* limping or not trusting a joint
* pain that gets worse with activity
* pain that **doesn’t improve** after rest
* pain that **wakes you up** at night
TeenThreads rule:
👉 “Sore” is normal. **“Something’s wrong”** is a message.
—
## Difference Between Normal and Abnormal State
### Normal recovery
* mild pain improves in 48–72 hours
* range of motion returns
* you can walk/jog without pain
### Abnormal recovery
* swelling/pain persists
* you can’t bear weight
* you feel unstable (“my ankle is giving up”)
* symptoms spread (numbness/tingling)
* you keep re-injuring the same spot
—
## Types (and Basic Differences)
### 1) Sprains vs Strains (most common confusion)
* **Sprain** = ligament injury (bone-to-bone)
* **Strain** = muscle or tendon injury (muscle-to-bone) ([MedlinePlus][2])
### 2) Fractures & Stress Fractures
* **Fracture** = bone breaks from a big force
* **Stress fracture** = tiny cracks from overuse (sneaky and serious)
### 3) Overuse Injuries
Often from training too much, too soon, or too repetitive:
* tendinitis
* shin splints
* stress fractures
* shoulder/knee overuse issues
AAP notes overuse injuries are a major chunk of youth sports injuries and gives prevention steps. ([HealthyChildren.org][3])
### 4) Growth-Plate Injuries (teen-specific)
Teen bones are still growing. Growth plates can be vulnerable during growth spurts.
### 5) Heat Illness (sports + hot weather)
Heat exhaustion/heat stroke risk increases with intense training + high temperatures. ([CDC][4])
### 6) Head Injuries: Concussion
A concussion can happen without being knocked out. CDC HEADS UP covers concussion symptoms and safety steps. ([CDC][5])
—
## Causes (Why It Happens)
* bad landing mechanics
* contact/collision
* poor warm-up
* weak core/hips (knee/ankle injuries rise)
* fatigue (tired body = sloppy form)
* too much training volume
* early sport specialization + year-round play (overuse)
* wrong gear/shoes
* dehydration/heat
—
## Risk Factors
* playing one sport year-round
* sudden training increase (tryout grind)
* previous injury (re-injury risk)
* poor sleep
* not enough rest days
* growth spurts (tight muscles + changing coordination)
—
## Who Is Vulnerable / Susceptible?
* teen athletes in high-volume club sports
* teens training for tryouts/varsity selection
* athletes returning too quickly after injury
* teens who don’t have access to athletic trainers/rehab guidance
—
## Complications (If Not Treated Well)
* chronic pain
* repeat injuries (ankle sprains that never heal right)
* long-term joint instability
* stress fractures worsening
* prolonged concussion symptoms
* burnout (mental + physical)
—
## Prevention (The “Future-Proof Athlete” Plan)
### The “70% Rule”
Don’t train at 100% intensity every day. Mix:
* skill days
* strength days
* recovery days
### Warm-Up That Actually Works
5–10 minutes:
* light cardio
* dynamic stretches
* sport-specific moves (jumps, cuts, footwork)
### Strength for Injury Armor
* core
* hips/glutes
* hamstrings
* ankles/feet stability
### Rest Days = Performance Days
AAP recommends steps to reduce overuse/overtraining and protect young athletes. ([Pediatrics Publications][6])
—
## How Sports Injuries Develop (The 2 Paths)
### Acute path
bad landing → pop → swelling → pain → reduced movement
### Overuse path
tiny irritation → keep playing → bigger irritation → pain daily → stress fracture / tendinitis
TeenThreads truth:
👉 Overuse injuries are the slow villains. They don’t look dramatic until they are.
—
## Common Symptoms (By Injury Type)
### Sprain/Strain
* pain + swelling
* bruising
* weakness or instability
### Fracture
* severe pain
* swelling/deformity
* can’t bear weight
### Overuse
* pain that starts during activity and later becomes constant
* tenderness in one spot
* performance drops
### Concussion (brain injury)
CDC symptom list includes headache, dizziness, nausea, light/noise sensitivity, “foggy” feeling, mood changes, and sleep issues. ([CDC][5])
—
## What Other Problems Can Look Like This?
* growing pains vs stress fracture
* shin splints vs stress fracture
* dehydration/fatigue vs concussion symptoms
* anxiety vs concussion dizziness/fogginess
If symptoms are confusing, get evaluated.
—
## Diagnosis and Tests
A clinician/athletic trainer may use:
* physical exam + range of motion tests
* strength and stability tests
* X-ray (fracture)
* MRI/ultrasound (soft tissue/stress injury)
* concussion evaluation tools + symptom tracking (CDC guidance) ([CDC][4])
—
## Treatment and Therapies (What Actually Helps)
### For many minor injuries: stop + early care
MedlinePlus recommends stopping activity and often starting with **RICE** (Rest, Ice, Compression, Elevation) for many minor injuries. ([MedlinePlus][7])
### Rehab is not optional
Physical therapy and progressive return rebuild:
* strength
* stability
* confidence
* movement patterns
### Concussion: “When in doubt, sit them out”
CDC says remove the athlete right away if concussion is suspected and keep them out the same day until cleared. ([CDC][8])
### Return-to-Play (Concussion) — stepwise
CDC outlines a **6-step return-to-play progression**, with provider approval and symptom monitoring. ([CDC][9])
### Return-to-School matters too
CDC notes many students can return to school within **1–2 days** with supports if symptoms remain. ([CDC][10])
—
## Statistics & Reality
* AAP emphasizes overuse and overtraining as major youth athlete issues and provides prevention recommendations. ([Pediatrics Publications][6])
* Concussion policy is tightening in many sports, including attention to repetitive head impacts in soccer (recent protocols). ([AP News][11])
—
## Alternative / Complementary Supports (Safe Add-Ons)
* sleep consistency (recovery hormone support)
* hydration + balanced meals
* gentle mobility work (when cleared)
* mental skills training (fear of re-injury is real)
Avoid “push through it” advice from random people online.
—
## New Treatment Approaches (Future-Facing)
* wearable sensors for load management
* baseline concussion testing and symptom apps
* smarter training programming (injury prediction models)
* better youth sport policies around head impacts ([AP News][11])
—
## Cost of Treatment / Management
Varies by injury:
* minor sprain care: low cost
* imaging + PT: moderate
* surgery/rehab: high
Schools/teams sometimes provide athletic trainers or PT referral pathways.
—
## Does Insurance Generally Cover Treatment?
Often covers:
* urgent care/primary care visits
* imaging (if medically indicated)
* PT (varies by plan)
* specialist care
Check your plan for sports injury PT visit limits.
—
## Prognosis
Most teen sports injuries heal well with:
* early recognition
* proper rehab
* gradual return
Trying to rush back is the #1 way to turn a short injury into a long one.
—
## What Happens If No Treatment/Support?
### “Pros” people think
* keep playing
* don’t lose position
* don’t disappoint anyone
### Real cons
* injury worsens
* more time out later
* permanent instability or chronic pain
* repeated concussions = longer recovery risk
* burnout/mental stress

## Living With a Sports Injury (Teen Life Edition)
**How to stay mentally okay**
* stay connected with your team
* do rehab like it’s training
* set small weekly goals
* don’t doomscroll “worst case” injury videos
**How friends can help**
* don’t joke about “weakness”
* walk with them to the nurse/trainer
* help them stick to rehab reminders
—
## Myths vs Facts (TeenThreads Reset)
**Myth:** “If I can walk, it’s fine.”
**Fact:** Stress fractures and serious sprains can still let you walk—at first.
**Myth:** “I didn’t black out, so it’s not a concussion.”
**Fact:** Most concussions don’t involve loss of consciousness. ([CDC][5])
**Myth:** “Ice fixes everything.”
**Fact:** Ice helps symptoms; rehab fixes function.
**Myth:** “Pain is weakness leaving the body.”
**Fact:** Pain is data. Use it.
—
## When to See a Doctor **Today**
Get urgent care if you have:
* suspected concussion symptoms (especially worsening headache, repeated vomiting, severe confusion)
* severe pain or obvious deformity
* can’t bear weight
* numbness/tingling
* swelling that rapidly increases
* fever or open wounds
* repeated re-injury of the same joint
For suspected concussion: remove from play and get evaluated. ([CDC][8])
