When snowboarding I get unbearable pains in my foot and major cramping in my calfs and quads. Why?

cracker asked:


This is my second year snowboarding. I get unbearable pain in my feet and my quads and calfs cramp up to the point I have to stop every ten seconds to relieve the pain. Is there something I can do to help it? I love snowboarding and fear of having to give it up because of the pain.
