In this episode, Jonathan Chang and Jason Robertson discuss an unusual recent case.  Some have noted that post-Covid patterns may involve the Shaoyin channel. When this pattern emerges, it often includes more familiar symptoms of insomnia, heart palpitations and some kinds of tinnitus. In this case, the primary complaint was a deep pain in the left shoulder joint.      Music by The Strayun.
