I flew the EMB-120 as well as played tennis in college and yes the awkward horn yoke can apply pressures to your tendons when turning right and left which can cause them to strain. I recommend looking to a Tennis Elbow brace; it should help by relieving some of the stress when applying force to the horns.

This problem probably stems from playing tennis as it did for me. I use the brace and shortly after my elbow returned to normal.

Best of luck!
