My left leg's interior LCL is popping when my left leg is extending (read: quad extension). I think it may have developed from overtraining. I cant find a cyst nor is it painful nor is there any site swelling. Anyone experienced something similar? If so, how did you treat it, if at all? I dont want to lift on it as tendon/ligament injuries can compound if they are neglected, but like most of you, I do not want to sideline myself any longer than necessary.

PS: I am aware that a doctor is an option but until it is determined that RICE will not fix this, that option is deferred.
