A friend lent me his CHI Palm when I had a labrum tear that wouldn’t resolve. Initially couldn’t raise my arm above my elbow. My ortho kept pushing a surgery but I insisted on physical therapy but it just wasn’t working. I could still not put my arm above my shoulder. After 4 days with my friends CHI Palm I could sense something different and was able to sleep on that side again. My buddy demanded his Palm back so I immediately purchased one. After two weeks I am near 90% improved. I was able to surf! Taking it slow but super impressed. You gave me my JOY back! Thanks YOU ALL!
