Hi, i injured my knee yesterday, it is an acute pain in the right knee, the front left inner part of it. whenever my knee makes a certain angle, such as in walking, it hurts. I think it's a sprained ACL... but I don't know that much about injury? Anyone have any suggestions on how to heal quickly...does RICE really work(Rest, Ice, Compression, Elevation)? I've heard that you actually want heat to promote blood circulation which in turn promotes healing. Ice the first 24 hours and then heat??? Here is a picture...no it's not my legs haha.
