Heard the term “tennis elbow”? Did you know that there is a similar condition called “golfers elbow”?
It is so similar in fact that it is the same pathology as tennis elbow, however the pain sits on the inside/underside of your elbow opposed to the outside/top.
Why is it called golfers elbow? As we swing down to strike the ball, our wrist flexor muscles help to create club-head speed by adding extra whip before impact. These flexor muscles (which attach to the underside of our elbow) are working extremely hard to brace for impact as the club hits the ball (or turf!). This causes them to forcibly lengthen- an eccentric contraction.
