A large proportion of sarcoidosis patients live with severe chronic pain despite the heavy use of painkillers, including opioids, a recent survey found.

In addition, pain considerably impacts their walking ability, sleep, and enjoyment of life. Based on the survey results, researchers argue that the nerve damage that causes pain in sarcoidosis may be more common than previously acknowledged.

The survey, which included more than 2,700 patients, was conducted by the Foundation for Sarcoidosis Research (FSR), working with the Cleveland Clinic and Araim Pharmaceuticals.
