Idiopathic Ankle Pain: A Case of Uncharacteristic Paresthesia

Idiopathic Ankle Pain: A Case of Uncharacteristic Paresthesia

An anomalous disorder that is often misdiagnosed is Complex Regional Pain Syndrome (CPRS). CPRS has two classifications (Type I & II) and is generally characterized by a combination of sensory, autonomic, trophic, and motor signs and symptoms. The most common ones include: severe pain that is disproportionate to the cause, joint stiffness, abnormal skin appearance, swelling, muscle weakness, and changes in sweating. This condition is most typically seen in the shoulder and ankle. The literature review demonstrated that there is no definite testing that can be done to diagnose this condition. In 1994 the International Association for the Study of Pain (IASP) created a set of diagnostic criteria that is primarily used in determining this condition. This criterion is believed by current research to be invalid and the importance of ruling out other possible conditions that present similarly is stressed. There is also no proven treatment method to cure CPRS. Currently physical therapy, psychological therapy, and medicinal treatments are performed, although the efficacy of each is questioned. This medical case review will identify one patient with the possible development of CPRS after sustaining an ankle sprain.
