I havent been diagnosed with sleep apnea but my doctors believe I have it so want me to do a sleep study. I have been diagnosed with sarcoidosis in the lungs and liver. I have found many people with RSd that have Sarcoid as well, just when you say your gasping for air thats what happened to me. The RSd doctors say that because of the RSD we are more prone of getting autoamuine disease such as sarcoid they say thats why I got mine.
