When Is Leg Pain in Children Normal Growth Pain—and When Is It a Cause for Concern?

Many of us remember waking up suddenly as children with leg pain—sometimes specifically around the hip joint—just before starting school. Our mothers would rush to our beds, comfort us, hug us, and gently reassure us that the pain meant we were growing. Often, she would happily share the news with the father the next morning, relieved that there was nothing to worry about.

However, a child’s complaint of leg pain or joint pain is not always a sign of normal growth pains. For this reason, NadorMagazine spoke exclusively with Dr. Mohammed Abed, Consultant Pediatric Orthopedic Surgeon, who explained an important question many mothers face: When does leg pain indicate a medical condition rather than natural growth pain? He clarified the differences between normal and abnormal joint pain in children as follows.

What Are Normal Growth Pains in Children?

Growth-related pain in bones and muscles is common and affects approximately 25–40% of children worldwide. These pains may cause children to wake up crying at night or stop playing due to discomfort.

Growth pains usually appear during two main age periods:

  • Between 3–5 years old

  • Between 8–12 years old

Although these pains are considered normal, there is no strong scientific evidence proving that bone growth itself causes pain. The more realistic explanation is muscle fatigue and strain caused by running, jumping, and physical activity during the day.

Symptoms of Normal Growth-Related Joint and Bone Pain

Growth pain is typically felt in the muscles rather than the joints. Parents should learn to distinguish between joint inflammation and normal growth pain.

  • Pain usually occurs in the front of the thighs, calf muscles, or behind the knees

  • Pain intensifies in the late afternoon or evening

  • It may sometimes wake the child from sleep

  • Pain severity varies from child to child

  • It is not usually present every day

During a medical examination, a doctor typically finds:

  • No pain when moving the child’s legs

  • Pain relief when the legs are gently massaged or pressed

In contrast, if the pain is caused by joint inflammation, the pain worsens during examination, and the child may cry when the doctor moves or touches the legs.

Tips to Reduce Growth Pain in Children

  • Gently massage the painful area using soothing oil or cream

  • Apply warm compresses indirectly (use a cloth to avoid direct heat)

  • Give child-safe pain relievers only as prescribed by a doctor

  • Never give aspirin to children under 12 years of age

When Is Joint Pain in Children Concerning?

Parents should be concerned if:

  • The pain is continuous and does not come and go

  • Pain occurs mainly in the morning

  • The child has difficulty getting out of bed or preparing for school

Signs of concerning joint inflammation include:

  • Redness or swelling around the joint

  • Increased warmth in the affected area

  • Fever

  • Muscle weakness in the leg

  • Difficulty walking or abnormal gait

If joint pain is accompanied by skin rash, loss of appetite, or persists for several days, the child should be seen by a doctor immediately. Some joint pain may signal autoimmune diseases such as juvenile rheumatoid arthritis or infections affecting the bones, which require prompt treatment to avoid serious complications.

The Link Between Leg Pain and Recovery from Influenza

Some children experience leg pain after recovering from influenza, especially around age four. This often occurs after taking antibiotics or fever-reducing medications without medical supervision.

Symptoms may include:

  • Pain in the calf muscles

  • Limping or inability to walk

  • Walking on tiptoes after recovery

This condition is often caused by viral muscle inflammation associated with Influenza A or B or other seasonal viruses. Treatment typically includes:

  • Child-appropriate pain relievers and anti-inflammatory medication under medical supervision

  • Rest and bed confinement

  • Plenty of warm fluids

Improvement usually occurs within three days.

Important Conditions to Differentiate

Parents must distinguish between post-influenza muscle pain and more serious conditions such as:

Guillain-Barré Syndrome

  • Begins with leg muscle pain

  • Progresses into ascending paralysis

  • May affect breathing muscles

  • Can be life-threatening if not treated promptly

Rhabdomyolysis (Muscle Breakdown)

  • Severe muscle pain

  • Dark-colored urine

  • Risk of acute kidney failure

Both conditions require immediate medical attention.
