Replying to Shin bang question..

Is it normal for your shins to have pain to some sort of degree 24/7? Like, its not super bad but it is kinda annoying. My boots fit me really well and the only thing i can think of that is causing the pain is landing back seat which is unavoidable when learning new tricks. So am i doing anything wrong or is sore shins just another aspect of freestyle skiing? Its not unbearable or anything but i Just want to know if i could take any more steps to prevent it all together..
