I have started practicing straight arm forehand a few weeks ago. Just after i take my swing, i turn my body and take the swing with a bend arm and my arm goes straight with the momentum and i hit the ball. The problem is i feel some pain after doing that, even the day after practice. I feel like my elbow cracks when the arm suddenly goes straight from elbow after swing. I don't know if i could explain it correctly but i'm afraid of developing tennis elbow. Anybody else experience lack of comfort when using straight arm forehand besides me ?
