Awkward landing injury

my friend (who was recently fitted properly for boots) sent a jump pretty deep and landed back seat on her left leg. she now has sharp pain down the left side of her leg (along the fibula). it hurts to walk and tilt her foot but not really to put weight on it. there is no bruising. little to no swelling and it hurts to lift her leg at certain angles. has anybody had a similar pain as this? i want to say its just regular old shin bang but she is a little worried its worse as she doesnt want to lose more of her season after fracturing her spine earlier in the season. she is going to hospital later but was just wondering what it was she's done.
