Complex regional pain syndrome (CRPS) is characterized by multifactorial pain disorder in combination with sensory, autonomic, trophic and motor abnormalities. CRPS type 1 refers to cases in which no specific nerve injury is identified, while type 2 are cases accompanied by identifiable nerve damage. Once considered to be a rare disorder among children and adolescents, CRPS has become better recognized over the past two decades. The clinical differences between adult and pediatric CRPS and the lack of specific laboratory tests and imaging techniques cause a delay in diagnosis of up to one year. Awareness of the syndrome is very important for the early diagnosis and treatment and is a positive prognostic factor. Here we present an 11-year-old male patient with pain, color changes of the skin and motor deficit in the right leg diagnosed with CRPS type 1. The patient responded well to rehabilitation and pregabalin treatment.
