Diagnostic Approach to Flank/Back Pain in Adolescents

Pain Characteristics

The American College of Physicians recommends asking about the exact location of pain, onset, duration, and progression of pain, as well as pain quality and intensity, to determine the underlying cause of flank/back pain in adolescents 1, 2
The American College of Physicians suggests inquiring about the timing of pain, including whether it is worse at night, morning, or with activity, to guide appropriate management 2, 3
The American College of Physicians recommends determining if pain radiates to other areas, such as the leg, abdomen, or groin, to assess for potential complications 1, 3

The American College of Physicians recommends asking what makes the pain worse, such as specific activities, positions, or movements, to identify potential triggers 1, 2
The American College of Physicians suggests determining what relieves the pain, such as rest, medications, or position changes, to guide treatment 1, 2

The American College of Physicians recommends inquiring about neurological symptoms, such as numbness, tingling, or weakness in the legs, to assess for potential neurological complications 1, 3
The American College of Physicians suggests asking about bowel or bladder dysfunction, such as incontinence or retention, to identify potential complications 1, 3

The American College of Radiology recommends asking about constant pain, night pain, or pain that wakes the patient from sleep, as well as pain persisting beyond 4 weeks, to identify potential red flags 4
The American College of Radiology suggests inquiring about systemic symptoms, such as fever, weight loss, or fatigue, to assess for potential serious pathology 4

The American College of Radiology recommends initial imaging with AP and lateral spine radiographs if symptoms persist beyond 4 weeks or if red flags are present 4
The American College of Radiology suggests considering MRI for persistent symptoms, neurological findings, or suspected serious pathology 4

The American College of Physicians recommends relative rest and activity modification based on symptoms, as well as application of heat for short-term pain relief 5, 6
The American College of Physicians suggests considering acetaminophen or NSAIDs for pain management if no contraindications are present 5, 6
The American College of Physicians recommends providing education about expected course and self-care options, as well as considering physical therapy for persistent symptoms 5, 6, 7

The American College of Physicians recommends scheduling reassessment in 2-4 weeks if symptoms persist, and considering earlier follow-up if symptoms worsen or new symptoms develop 1, 8
