What If It Isn’t Growing Pains?

Leg aches in children are often labeled as “growing pains.” While true growing pains are common and harmless, it’s important to recognize when a child’s discomfort may signal something else. If you’ve noticed that your child’s aches don’t fit the usual pattern, read on to learn about other possible causes, red-flag symptoms, and steps you can take to get answers.

Understanding True Growing Pains

Before exploring other causes, here’s what classic growing pains look like:

• Age: 3–12 years old
• Timing: Late afternoon or evening; may wake the child at night
• Location: Both calves, shins, thighs or behind the knees (rarely in joints)
• Pattern: Comes and goes over months; pain intensity varies
• Exam: Child is completely normal between episodes

If your child’s discomfort doesn’t match this pattern, consider the possibility of child leg pain not growing pains.

Common Causes of Child Leg Pain Not Growing Pains

1. Injury

   • Sprains and strains: Twisting or overuse can inflame muscles, ligaments or tendons.
   • Fractures: Even hairline breaks may cause persistent pain, swelling or bruising.
   • Growth plate injuries: The softer cartilage at the ends of growing bones is vulnerable to trauma.

2. Overuse Conditions

   • Osgood-Schlatter disease: Painful bump below the kneecap in active preteens.
   • Sever’s disease: Heel pain in physically active 8–14-year-olds.
   • Shin splints: Tenderness along the shin bone after repetitive impact.

3. Inflammatory and Autoimmune Diseases

   • Juvenile Idiopathic Arthritis (JIA): May cause joint stiffness, swelling and limited range of motion.
   • Reactive arthritis: Joint pain following infection elsewhere in the body.

4. Infections

   • Osteomyelitis: Bone infection causing severe pain, fever and redness over the affected area.
   • Septic arthritis: Infection within a joint—urgent treatment needed to prevent permanent damage.
   • Cellulitis: Skin infection that can spread to deeper tissues.

5. Bone Disorders and Tumors

   • Benign bone tumors (e.g., osteochondroma): Often painless but can cause discomfort if they press on nerves or muscles.
   • Malignant tumors (e.g., osteosarcoma, Ewing sarcoma): Rare but serious—persistent pain, night pain, swelling and sometimes systemic symptoms like weight loss or fever.

6. Neurological Causes

   • Growing pains are not nerve-related, but neuropathies or radiculopathies (nerve root irritation) can cause sharp, shooting or burning pain.
   • Conditions like peripheral neuropathy or spinal issues (e.g., herniated disc) are less common in children but should be considered if pain is severe or associated with neurological signs.

Red-Flag Signs to Watch For

Prompt medical evaluation is recommended if any of these appear:

• Pain that
  • Is severe or progressive
  • Wakes the child up night after night
  • Doesn’t improve with rest or over-the-counter pain relievers
• Swelling, redness or warmth over bone or joint
• Fever, chills or other signs of systemic illness
• Limping, refusal to bear weight or use the leg
• Noticeable deformity or misalignment
• Unexplained weight loss or loss of appetite
• Neurological symptoms (numbness, tingling, weakness)

What to Do Next

1. Initial Home Care

   • Rest: Limit high-impact activities for 1–2 days.
   • Ice: Apply for 15–20 minutes, 3–4 times daily to reduce swelling.
   • Elevation: Keep the leg propped up to minimize fluid buildup.
   • Over-the-counter pain relief: Acetaminophen or ibuprofen per dosing guidelines.

2. Observe and Document

   • Keep a pain diary: Note time of day, intensity (scale 1–10), duration, and any triggers.
   • Photograph any visible changes: Swelling, bruising or redness.
   • Track activity levels: Note any recent increases in sports or play.

3. Use an Online Symptom Checker
   For a head start on understanding potential causes, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. This tool can help you organize symptoms before your medical appointment.

4. Schedule a Medical Evaluation

   • Your pediatrician will perform a physical exam, looking for tenderness, range-of-motion limits or signs of inflammation.
   • Blood tests may screen for infection or markers of inflammation (e.g., ESR, CRP).
   • Imaging:
     • X-rays to detect fractures or bone abnormalities
     • Ultrasound for joint fluid or soft-tissue issues
     • MRI if deeper structural or nerve problems are suspected

5. Referral to a Specialist

   • Orthopedist: For bone, joint or growth-plate concerns.
   • Rheumatologist: If juvenile arthritis or autoimmune disease is suspected.
   • Infectious disease specialist: For complex or persistent infections.

Preventing Overuse Injuries

• Balanced activity: Mix high-impact sports with low-impact ones (e.g., swimming, cycling).
• Proper footwear: Ensure shoes fit well and provide adequate support.
• Warm-up and cool-down: Gentle stretching before and after exercise.
• Strengthening exercises: Focus on core, hip and leg muscles for stability.
• Rest days: Schedule regular breaks to allow recovery.

---

Supporting Your Child

• Validate their pain: Let your child know you take their discomfort seriously.
• Encourage gentle activity: Complete rest can lead to stiffness—offer short, soothing walks if tolerable.
• Teach body awareness: Help them recognize early signs of overuse (tightness, mild soreness).
• Keep communication open: Regularly ask about new symptoms or changes in pain patterns.

When to Seek Immediate Care

If your child experiences any of these, call emergency services or go to the nearest ER:

• Sudden inability to move the leg or bear weight
• Sudden, intense pain that seems out of proportion
• High fever (above 102°F or 39°C) with leg pain
• Signs of severe infection: Rapid swelling, redness spreading quickly, chills

Key Takeaways

• Not all leg pain in children is growing pains.
• Pay attention to the pattern, timing and severity of pain.
• Watch for red-flag signs that suggest a more serious condition.
• Use home care measures but don’t delay evaluation if concerns persist.
• A free, online symptom check, using the doctor approved Ubie Symptom Checker can help you organize symptoms before seeing a clinician.
• Always speak to a doctor if anything could be life-threatening or serious.

Your child’s health is worth proactive attention. If in doubt, reach out to your pediatrician or seek urgent care when red-flag signs appear.
