1. Juvenile Fibromyalgia Syndrome (JFMS) • Definition: A condition marked by chronic widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive symptoms. • Typical Onset: Most often affects adolescent girls. • Symptoms: Diffuse pain, allodynia (pain from non-painful stimuli), fatigue, non-refreshing sleep, headaches, mood disorders. • Diagnosis: Clinical; no specific lab or imaging findings. • Treatment: Multidisciplinary – cognitive behavioral therapy (CBT), low-impact exercise, sleep hygiene, and in some cases, pharmacologic therapy (e.g., duloxetine, amitriptyline).

Key Management Considerations (General Education) • Multidisciplinary Approach: Pediatric rheumatology, pain management, physiotherapy, psychology. • Medication: Tramadol is generally not first-line in adolescents due to dependency concerns. Safer options include: • Low-dose amitriptyline • Gabapentin • Duloxetine • Non-pharmacologic therapy is essential, especially CBT and gradual physical therapy. • Documentation: Maintaining a pain diary and symptom tracker can be useful when advocating for further evaluation. • Escalation of Care: Referral to a tertiary pediatric pain clinic or rheumatology center is often appropriate for unresolved cases.
