Massage Ball on a String
In 2019 I developed pain in my racquet arm that got so bad I couldn’t extend it across my body to hit a backhand. I went to my local Airrosti clinic for diagnosis and treatment. The source of the arm pain was traced to tightness in my shoulder. Part of the rehabilitation that was prescribed was use of a lacrosse ball for myofascial release of adhesions in the shoulder. It worked.
