Should I be using heat instead of ice for foot injuries from kicking an elbow?

Accidentally kicked elbow with my foot, directly below the ankle. It swelled up immediately. I have dealt with this injury before and I typically just employ the RICE method for a week or so.

These days I’ve been hearing from people that ice actually hinders the healing process and that the new school of thought is to use heat to promote(?) the inflammation to heal faster.

Wondering what the best method is here.
