knee and calf pain
I started experiencing knee and calf pain when I went to the bathroom. My knee suddenly gave out. Currently, I experience shooting pains down my calf. I can walk on the leg, but gingerly. I cannot bend the leg with out pain. I currently rotate between walking 5 miles, Tae-bo exercise for 45 minutes or walk up a 1.4 mile mountain 4-5 times a week. I did not experience pain doing any of these exercises.How can I treat the injury?
