question: Hi, I sprained my ankle last week due to a fall and had it xrayed. I unfortunately thought nothing of the tenderness to my knee at the time and didn t mention it to the doctor. The tenderness has not improved at all. In fact a small area to the right of my left knee cap is extremely sore to touch or if I lean it against something. Could this be something more serious than a simple bruise as I first thought it was? Many thanks
