[|Human|] 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!
[|AI|]  Hello. Thank you for writing us here. The most common cause could be injury to her common perineal nerve on the knee joint which causes symptoms of tingling sensation and numbness of her leg. You can apply a bandage, so her feet is immobilized and give her diclofenac sodium for pain. Also, I would suggest you to see an orthopedic for proper management. She could be told for bed rest and application of a plaster for immobilization of the limb. Best regards, Chat Doctor.
