question: My daughter sprained her ankle playing volleyball 3 days ago. x-rays showed no broken bones. the issue im having is the leg, past the knee is visably a couple shades darker than the other leg and is cold (ice) to touch. I took her back to er, they couldn t answer as to why it was that way. she has numbness, tingling, in the knee. and of course there is still a lot of pain. she will not put any weight on it. she is 15. Ive iced it q2hours at night and its been elevated during school hours...HELP!
