RSDSA is a 501 (c)3 tax exempt organization. Founded in 1984, we are the oldest organization dedicated to supporting the CRPS community, funding research to find better treatments and ultimately a cure for this rare disease that afflicts people with chronic, potentially debilitating pain. In addition to viewing our audit and annual accomplishments, you may find additional information about our activities and success stories throughout this website. We are also available to speak with you one-to-one about support opportunities. Thank you for your interest in RSDSA.
