Heat or cold: How should ballet dancer treat a sore knee?

I dance ballet, and on one of the jumps, called a tour jeté, I used to land more heavily on my right heel. Done repetitively, it caused some trauma to the left uppermost corner of my right kneecap. I've since modified my technique, but I still land with my weight more on the heel on some of the jumps. Eventually, I feel pain, and it is difficult to kneel on that knee. (I don't have the same experience with my left knee.)
