Sore Knees Apply ice, and try to rest. If you haven't already, be sure that your bindings have been adjusted by a ski shop. Go easy the next day. No bumps or aggressive skiing. Have the medical clinic check your knees if they're really sore.
More severe pain requires immediate medical attention.
Also don't place hands in pole straps. If you fall, your thumb can easily sprain if the hand is caught in the strap. The pole can also whip back at you. Before you ski, stretch your calf muscles. If you're a beginner, slow down on moguls.
