Complex Regional Pain Syndrome (CRPS) is a condition characterized by progressive and painful decreased joint flexibility, which is exacerbated after a certain progression by bone demineralization. It is often a side-affect
of a surgical operation, a major or even minor trauma, a sprained ligament, or any other joint damage. This illness causes chronic pain which is responsible for a lack of mobility. Tests (x-ray, MRI) may be necessary in eliminating any other diagnoses. An early diagnosis allows for more adapted treatment through physical therapy, often accompanied by corticosteroid injections.
