tenonitis

It turned out to be tenonitis.

Tenonitis is a rare eye disease, an inflammation of the Capsule of Ténon.

During the last novel in this series I developed tenonitis (also spelled tendi- nitis), an inflammation of the tendon that causes pain when I move my arm beyond a certain range.

Thus the main character of this novel is Tale Teller, who today would be called a free-lance writer, with an incapacity of the arm similar to what I experienced during my bout with cat scratch fever and later with tenonitis.
