Discover what causes growing pains, when they usually appear, and the best ways to comfort your child safely and effectively at home.
What are growing pains? Growing pains are harmless muscle aches or throbbing sensations that affect children ages 3 to 12. They typically occur in both legs (calves, thighs, or behind knees) during late afternoon or night and resolve by morning without causing long-term damage.
On FamilyNes, we’ll explore what growing pains really are, when they typically occur, and the best ways to soothe your child’s body naturally.
What Are Growing Pains in Children?
As your child grows, you might notice moments when they complain about leg aches, especially after an active day of running or playing. These experiences, often referred to as growing pains, can be confusing for parents who aren’t sure what’s causing the discomfort. Although these aches are a normal part of early childhood development, knowing how to spot them can give you peace of mind and help you keep your little one calm and comfortable.
Common Symptoms & Characteristics
Growing pains vary from child to child, but they generally share specific features that set them apart from injuries or illness:
- Affects both legs: Discomfort usually occurs in both legs simultaneously, most often in the calves, front of the thighs, or behind the knees.
- Muscular, not joint pain: The aches occur within the muscle tissue rather than inside the joints.
- Late-day timing: Aches typically start in the late afternoon, evening, or wake children up during the night.
- Gone by morning: The pain usually resolves completely after rest, allowing your child to wake up feeling normal with no morning stiffness or limping.
Who Gets Growing Pains? (Age Range & Timing)
Growing pains most frequently affect children between the ages of 3 and 12 years old. They often occur in two distinct stages: early childhood (ages 3 to 5) and pre-adolescence (ages 8 to 12).
What Causes Growing Pains?
The exact cause of growing pains isn’t fully understood, but experts agree that they are not directly caused by bones growing. Bone growth happens far too slowly to cause sudden or sharp discomfort. Instead, doctors and pediatric specialists believe growing pains stem from a combination of physical activity, muscle overuse, and natural fatigue.
Main Contributing Factors
- Muscle Fatigue & Overuse: Children are naturally energetic. Running, jumping, climbing, and playing throughout the day put significant strain on developing muscles and tendons. By evening, this intense physical activity can lead to dull or throbbing muscle aches.
- Flexible Joints & Posture: Some children have naturally hypermobile (flexible) joints or flat feet, which can cause their leg muscles to work harder during daily activities, leading to nighttime fatigue.
- Lower Pain Threshold or Fatigue: Growing pains tend to feel more intense when a child is overly tired, stressed, or emotionally drained at the end of a long day.
Why Joints Are Not Affected
It’s essential to note that growing pains affect muscles, not joints. They do not cause swelling, redness, warmth, or joint stiffness.
Because growing pains are a harmless part of early childhood development, they do not cause long-term damage or impair physical growth. Recognizing these physical triggers can help parents anticipate active days when nighttime aches are more likely to appear.
How to Deal with Growing Pains: 4 Comfort Tips
When your child wakes up in the middle of the night with leg aches, quick and gentle care can help them feel safe and return to sleep quickly. Below is a quick guide to home remedies, followed by step-by-step relief techniques.
Relief Method | How It Helps | Best Time to Use |
| Gentle Massage | Relieves muscle tension & relaxes tired legs | During active nighttime pain |
| Warmth & Heat | Increases blood flow to soothe aching muscles | Right before bed or during pain episodes |
| Leg Stretches | Improves flexibility & prevents muscle tightness | Late afternoon or evening routine |
| OTC Pain Relief | Reduces persistent discomfort under doctor guidance | When physical remedies aren't enough |
Gentle Leg Massage
A soothing leg massage works wonders to ease tight, fatigued muscles.
- Use slow, circular motions with your hands to gently rub your child’s calves, thighs, or behind their knees.
- You can use a small amount of baby lotion or warm oil to make the massage more comfortable.
- Many children find the gentle physical touch deeply comforting and fall back asleep while receiving a massage.
Apply Heat (Warm Bath or Heating Pad)
Warmth helps tight muscle fibers relax and increases circulation to sore areas.
- Warm bath: Give your child a warm bath right before bedtime, especially after days filled with heavy running or sports.
- Heating pad or warm compress: Apply a heating pad set to low (or a warm, damp cloth) to the aching legs for 10–15 minutes. Always check the temperature against your own wrist first to prevent skin burns.
Gentle Leg Stretches Before Bed
Simple stretching during the evening routine keeps leg muscles flexible and reduces the likelihood of nighttime cramps.
- Calf stretch: Have your child stand facing a wall, place their hands against it, and step one foot back while keeping their heel on the floor.
- Thigh (quad) stretch: While standing, gently bend their knee backward and hold their foot toward their buttocks.
- Hold each stretch gently for 10–15 seconds without bouncing.
Safe Pain Relief Options
If massage and warmth are not enough to comfort your child, over-the-counter (OTC) medication can help manage discomfort, always with the pediatrician's approval.
- Pediatric Pain Relievers: Children's acetaminophen or ibuprofen can be given according to dosage instructions based on your child's weight and age.
- Safety Warning: Never give aspirin to children or teenagers, as it is associated with a rare but serious condition called Reye’s syndrome. Always consult your pediatrician if you are unsure about proper dosages.
Growing Pains vs. Serious Conditions: When to See a Doctor
While growing pains are completely harmless, leg pain in children can sometimes point to an underlying medical issue, such as an injury, infection, or joint condition.
Knowing the difference between typical growing pains and red flag symptoms ensures your child receives the right care when they need it most.
Growing Pains vs. Other Conditions
Feature | Growing Pains (Normal) | Medical Concern (See a Doctor) |
| Location | Both legs (muscles) | Single leg or specific joint |
| Timing | Late afternoon, evening, or night | Daytime pain or pain during activity |
| Morning Symptoms | None (child wakes up feeling fine) | Limping, stiffness, or trouble walking |
| Physical Signs | Normal appearance (no swelling/redness) | Swelling, warmth, redness, or fever |
Red Flag Symptoms Parents Shouldn’t Ignore
Contact your pediatrician if your child experiences any of the following warning signs:
- Persistent or worsening pain: Pain that lasts into the morning, occurs throughout the day, or interferes with daily play.
- Single-leg pain: Pain that constantly affects only one leg, knee, or ankle rather than both sides.
- Visible physical signs: Swelling, redness, warmth, or tenderness around any joint or muscle.
- Limping or mobility issues: Difficulty walking, putting weight on a leg, or unusual morning stiffness.
- Systemic symptoms: Pain accompanied by fever, sudden weight loss, loss of appetite, or unusual fatigue.
Frequently Asked Questions
At what age do growing pains usually start?
Growing pains most commonly start in early childhood between ages 3 and 5, and often reappear during a second phase between ages 8 and 12. They typically stop altogether by early adolescence.
Where do children typically feel growing pains?
Children feel growing pains in the muscles of both legs—most frequently in the calves, the front of the thighs, and behind the knees. Growing pain does not affect the joints.
Do growing pains happen in arms or joints?
No, growing pains do not occur in joints. They affect muscle tissue, not bones or joints. While mild muscle aches in the arms occur occasionally, growing pains almost exclusively affect the lower legs. Pain centered in the joints or arms warrants a quick evaluation by a doctor.
How long do growing pains last?
A single growing pain episode usually lasts anywhere from 10 to 30 minutes, though some can persist for a couple of hours. Episodes can occur several nights in a row or disappear for weeks or months at a time before returning.
