From the Guidelines
The most appropriate next step in management of this 6-year-old boy with bilateral leg pain is observation and reassurance (option A). The clinical presentation is classic for growing pains, a benign condition characterized by intermittent, bilateral leg pain that typically occurs at night and improves with massage or analgesics. Several key features support this diagnosis: the pain has been present for 3 months without worsening, occurs only at night, improves with massage and over-the-counter pain medications, and does not interfere with daytime activities.
- The absence of fever, weight loss, or abnormal physical examination findings (no tenderness, swelling, or gait abnormalities) argues against more serious conditions like infection, malignancy, or orthopedic problems.
- Growing pains are a diagnosis of exclusion but are very common in children aged 3-12 years.
- According to the American College of Radiology Appropriateness Criteria, imaging is not recommended in the absence of red flags 1, and this patient's presentation does not suggest any red flags that would necessitate immediate imaging. Parents should be reassured about the benign nature of the condition and advised to continue with simple measures like gentle massage, warm compresses, and occasional over-the-counter analgesics like acetaminophen or ibuprofen when needed.
- More invasive testing like bone scans, blood work, or radiographs are unnecessary given the classic presentation and normal physical examination. The patient's ability to walk, run, and play without complaint during the day further supports the diagnosis of growing pains, as it indicates that the pain is not significantly impacting his daily activities or overall quality of life.

Diagnosis and Management of Leg Pain in Children
The patient's symptoms of bilateral leg pain occurring at night, primarily in the thighs, with improvement after massage or over-the-counter analgesics, are consistent with growing pains 2, 3, 4. The absence of fever, chills, weight loss, and trauma, as well as a normal physical examination, further supports this diagnosis.
Key Characteristics of Growing Pains
- Bilateral lower extremity pain, usually occurring at night 2, 3
- Pain is not caused by activity and does not cause a limp 3
- Normal physical examination, with no swelling, tenderness, or limited range of motion 2, 3, 4
Appropriate Next Steps
- Observation and reassurance are the most appropriate next steps in management, as growing pains are a self-limiting condition 2, 3, 4, 5
- Symptomatic treatment with massage and over-the-counter analgesics can be employed to alleviate pain 2, 3, 4
- Reassurance to the patient and parents about the benign nature of the condition is essential 5
