I've been able to do Triple Toe loops off the ice for a few months now and in the past week I've gotten to the point where I can get the rotations on the ice as well (though it's a fall or double-foot half the time). However, my landing knee is extremely sore now. It's physically more difficult for me to walk and when bending it sharply there are definitely "pop" noises. Should I be getting this checked out more closely? Money is an issue, though....I can't afford for a hospital visit.
