Dr. Shah -
Saturday, after a relatively easy (pace wise) but technical trail run, I developed a pain behind my right knee. I'm not sure of the cause. I will say that I did bruise the right knee a week ago during a 25K trail race. But at that time, the back of the knee did not hurt. I did do an easy trail run yesterday, but I think this may have been a mistake, since the pain seems worse today.
The pain comes when I do a number of things: For instance, if I am in a sitting position and raise my right leg (with the knee bent) I feel the pain right behind the knee. When I stand up from a sitting position, I feel pain behind the knee as well. When I am sitting, and I extend the right leg, I feel the pain as well.
When I am standing, feel the pain as well when I bend my leg (ankle toward butt).
