“Toughness” is part of youth-sports culture. The kid who plays through is praised; the kid who sits is sometimes labeled. Most of the framework parents and coaches inherit on this question is wrong for kids specifically.
The pediatric musculoskeletal system is different from the adult one. The “shake it off” answer that worked for the parent in their playing days produces growth-plate damage, chronic injuries, and longer-term problems when applied to a 13-year-old.
This piece is the framework.
The categories of pain.
Three distinct categories that the pediatric-sports-medicine literature distinguishes:
Soreness. Diffuse muscle ache the day after hard practice. Affects both sides equally. Improves with light movement. Resolves in 24 to 72 hours without specific treatment. This is normal training response. Playing through is appropriate.
Discomfort. A specific area that aches during activity but does not affect performance. No swelling, no point tenderness, full range of motion, full strength. This is the gray zone. May be early overuse, may be normal. Worth monitoring.
Pain. Sharp, localized, specific. Limits performance. May have swelling, point tenderness, or visible deformity. Affects one side. Gets worse with activity, not better. This is injury. Playing through is harm.
The kid who says “it just hurts a little, coach” needs the framework, not the toughness narrative.
The four signs that say sit.
One. Point tenderness over a bone. Press on a specific spot. If pressing produces sharp pain that the kid points to and confirms, that is a flag for bone or growth-plate injury. Sit and evaluate. Often imaging warranted.
Two. Pain that affects gait, throwing motion, or sport-specific mechanics. The kid is limping, hitching, or compensating. Continuing to play in compensation patterns produces secondary injuries.
Three. Swelling or bruising. Visible inflammation. The body is telling you something. Sit until evaluated.
Four. Pain that does not warm up. Most training soreness improves after the first 10 to 15 minutes of warm-up. Pain that stays the same or worsens through warm-up is injury, not soreness.
Any one of those, the kid is out for the rest of the practice or game. Pediatrician or athletic trainer evaluation before next practice.
The pediatric-specific concerns.
Growth plates are weaker than the surrounding bone in growing kids. A force that produces a “sprain” in an adult can produce a Salter-Harris fracture in a 12-year-old. Hand-finger-fracture-triage and similar pediatric injury pieces cover this in detail.
Persistent throwing-arm pain in a youth baseball or softball pitcher is rarely “just tendinitis.” It is often a flag for a stress reaction at the growth plate (Little League shoulder, Little League elbow). Playing through produces avulsion fractures and chronic issues.
Heel pain in a 9 to 13-year-old runner or jumping athlete is often Sever’s apophysitis (growth-plate inflammation at the heel). Modify activity, ice, gentle stretching. Persistent pain warrants podiatrist or sports-medicine evaluation.
Knee pain at the front of the knee in a 10 to 14-year-old is often Osgood-Schlatter (growth-plate inflammation at the tibial tubercle). Same approach.
Back pain in an adolescent gymnast or cheerleader is often spondylolysis (stress fracture in the lumbar spine). The kid who has persistent back pain for more than a few days needs imaging.
The pattern across all of these: pediatric overuse injuries often resolve with modification and rest. Playing through them turns recoverable injuries into chronic problems.
The conversation with the kid.
The kid wants to play. The kid is being told by friends, sometimes by coaches, sometimes by parents that toughness matters.
The conversation that lands:
“Toughness is not pretending nothing hurts. Toughness is telling the truth about what hurts and getting the help to come back fully.”
“The kid who plays through a real injury misses more weeks later than the kid who sits for one practice now.”
“You can be a great teammate, a hard worker, and someone who reports pain accurately. Those are not opposing values.”
The framework works better than guilt or fear. The kid can opt into the version of toughness that includes honesty.
The conversation with the coach.
Coaches set the cultural tone. The coach who praises the kid who plays through is the coach who incentivizes hiding pain. The coach who says “tell me if something hurts so we can address it together” is the coach who gets accurate reports.
The published research from National Athletic Trainers’ Association (NATA) on coach-influenced injury reporting is consistent: coaches who explicitly frame honesty about pain as part of being a good teammate get more accurate reports than coaches who frame toughness in opposition to honesty.
The “I just don’t want to disappoint the team” pattern.
Many adolescent athletes underreport pain because they do not want to let the team down. The frame is theirs; the source is often the team culture.
For the kid stuck in this pattern:
“Your teammates need you for the long season, not just today’s game. The kid who sits today and plays in May is more valuable than the kid who plays today and is out for May.”
“You disappoint the team more by hiding an injury that gets worse than by sitting for one game.”
The “we’ve already paid for this” pressure.
Tournament weekends, championship games, college-coach-watching showcases. These are the moments where pain gets hidden most. The cost of pulling the kid is real and the social pressure is high.
The math is honest: a kid who plays through a real injury at the showcase often performs worse than they would healthy, signals lower than they would healthy, and risks the rest of the season. The “we paid for this” investment is protected by getting an accurate evaluation, not by playing through.
The athletic trainer is the right tool.
For programs with an athletic trainer, the trainer is the first stop. They have the training to distinguish soreness from injury, to make return-to-play decisions, and to coordinate with physicians.
For programs without an athletic trainer, the pediatrician or pediatric sports-medicine clinic is the right starting point for any pain that meets the four-signs criteria.
The honest read. Playing through pain is sometimes the right call. Pediatric overuse and growth-plate injuries are not the situations where it is. The four signs, the kid’s honest report, and a culture that does not punish honesty are the framework. Programs and families that operate this way produce kids who play longer, healthier, and recover faster when something does go wrong.
For the parent: when your kid tells you something hurts, take it at face value first. The cost of believing them and being wrong is small. The cost of dismissing them and being wrong is much larger.
