New Study: Growing Pains as a Possible Early Migraine Symptom

Many children experience recurring leg pain labeled as “growing pains,” often dismissed as benign and self-limiting. But new prospective data suggest that in children with a family history of migraine, these pains may be an early warning sign. Could growing pains be the first symptom in a larger neurovascular picture? Let’s explore the research and clinical implications.

Growing Pains or Early Migraine?

Growing pains affect up to half of all children at some point in early development. These vague, deep aches in the legs—typically at night—are often considered harmless and attributed to musculoskeletal growth. But recent research challenges this view, especially in children with a family history of migraine.

A 2023 prospective study published in Cephalalgia Reports followed 100 children born to mothers with diagnosed migraine. The researchers set out to test whether growing pains may be an early, underrecognized symptom in the migraine spectrum.

Key Findings from the Study

• A Strong Predictive Pattern:Of the children who experienced growing pains, 76% went on to develop migraine or probable migraine over the 5-year follow-up period. In contrast, only 22% of those without growing pains developed migraine. The association was statistically significant (p < 0.001), pointing to a clear predictive trend.

• Temporal Clues:In many cases, the limb pain preceded the onset of migraine headaches—suggesting that what we call “growing pains” may actually be early manifestations of migraine physiology in the developing nervous system.

• Shared Neurological Features:The study builds on prior research suggesting overlapping mechanisms between growing pains and migraine, including altered pain processing, familial patterns, and circadian rhythms of symptom onset.

Why This Matters in Practice

For pediatric clinicians, especially those in integrative or neurodevelopmental care, this study offers a compelling reason to reassess the way we talk about—and track—growing pains. Rather than dismissing them as a normal part of childhood, we may need to consider:

1. Family history of migraine or chronic headache
2. Co-occurring symptoms like photophobia, sleep disturbance, or motion sensitivity
3. Emotional or behavioral changes surrounding pain episodes
4. Whether the pain is bilateral, episodic, and primarily occurs at night

A Shift in How We Screen and Support

This isn’t about overpathologizing childhood symptoms. It’s about catching patterns early, offering preventive guidance, and partnering with families who may already feel dismissed by previous providers.

In an integrative framework, this might mean:

1. Tracking limb pain episodes more deliberately
2. Screening for early migraine features in well-child visits
3. Offering supportive interventions for sleep, stress, and inflammation
4. Educating families on possible trajectories and when to refer to neurology

The Takeaway: Growing Pains Deserve a Second Look

For decades, growing pains have lived in a diagnostic gray zone—acknowledged but rarely explored. This new study gives us reason to pause and reconsider what these symptoms might really be signaling, especially in migraine-prone families.

As pediatric providers, reframing how we approach common complaints like growing pains could open the door to earlier support, better outcomes, and more informed conversations with families.
