Freestyle Back pain

Hurt my back today on the lake riding my buddies sj. Didn't actualy feel it hurt till I got off. Now I'm siting in the ER with killer lower back pain. Any buddy no why this would happen the only thing really any diffrent between his ski and mine is he has a shorter pole. Could that be why I'm hurting or is it just couse I'm a puss.
