Observe & prepare safely
During ordinary play, note which activity triggers pain, where the child points, whether there is limp/swelling, and how long recovery takes. Avoid repeatedly pressing or deliberately provoking pain.

Child leg pain during running or hopping: when is it more than “growing pains”?
Activity-triggered daytime leg pain deserves a different history from classic nighttime growing pains. A useful next step is to document natural episodes, functional change and any focal findings, then use a focused pediatric musculoskeletal examination to decide whether testing is needed.
This page is general research orientation. It cannot diagnose you or determine that it is safe to delay medical care.
Initial research compass
Three ways to make the next step more informative.
Audit records & evidence
Review growth, vitamin D or other labs only in context; note whether the child has ever had a focused hip-to-foot musculoskeletal and gait examination.
Bring a focused question to a clinician
Bring the child's usual play shoes and the natural-episode log to the pediatrician and ask for a focused exam before assuming either 'growing pains' or ordering broad testing.
Important: these are research-orientation ideas, not instructions to self-diagnose, stop prescribed treatment, or perform unsafe home testing. If symptoms may be urgent, seek appropriate in-person care first.
Why a deeper interview can help
A short web page cannot reconstruct a longitudinal medical case.
A full WhatDx case can ask follow-up questions based on your answers, review the records you upload, reconstruct chronology, track treatment response and compare competing explanations across specialties. It then produces a research dossier that you can discuss with a clinician.
The free suitability check is the right next step if you want a case-specific answer about whether that process is likely to add value.

Before you use this guide.
Is this page telling me what condition I have?
No. The same symptom pattern can have many causes, and this page does not have your full history, examination or records. It is intended to organize useful questions, not name a diagnosis.
What if my previous tests were “normal”?
Normal results can be genuinely reassuring, but their meaning depends on what was tested, when it was tested and which question the test can actually answer. A research process can help map that context without assuming that “normal” means “nothing is wrong.”
What does the paid WhatDx session provide?
A detailed adaptive interview, record review, a persistent 90-day case state and an evidence-linked research dossier. It is research support, not prescribing or treatment.
