PY - 2013 T2 - CURRENT Diagnosis & Treatment: Rheumatology, 3e AB - Consider when limb injury causes unexpectedly severe or prolonged distal pain.The complex regional pain syndrome (CRPS) diagnosis also requires regional microvascular dysfunction (edema or abnormal skin color or temperature).Posttraumatic neuralgia (PTN) does not require microvascular dysfunction.CRPS often devolves through PTN as it heals.Variably present symptoms not required for the diagnosis of CRPS include disordered movement, sweating, and posture (eg, dystonia).Symptoms can be mild and transient, moderate, or severe and prolonged. Severe and prolonged symptoms are uncommon. Cases that are not associated with trauma may have an internal cause that requires attention. Such cases comprise a minority of CRPS cases.
