After the previous post, I ran for 2 more times and then I stopped running because I felt that I needed to let the knee rest.
And then there is the feeling of discomfort in my knees, especially the right one, with no sign of getting better.
Do I need to train my leg muscle in order to get well? As the previous post suggested, there are 4 kinds of muscle I need to work with. Do I really need to train all 4 kind of muscle? Or is there a type of muscle held more responsible to the pain?
