As stated in his biography, in a match in 1994, Arn was thrown into the ring ropes. The top rope broke from the turnbuckle, but he was able to land on his feet. Six months later, the same event happened again, but this time he landed full-force on to the concrete and hit his head, neck, and upper back. He never took time off to heal. As time passed, with no down time, the injuries worsened. In his biography, Anderson states that the first sign of problems was, during a match, his left arm suddenly went numb and unresponsive. Later on, they found a rib, possibly torn away from the spine during the accident, was popping in and out of joint, causing shoulder discomfort and weakness.
