A week ago I feel on the ICE I have some bad bruises on my knees one really bad! I have a really hard knock on one and I can barely walk on it I can't straighten it out please help me ASAP?

Severe knee contusio. A sharp blow to both knees by falling directly on ice can be a significant amount of force. Thus if one can't fully straighten the knee or bear full weight u need to be evaluated soon as u may have a fracture.
