Just for information: I was watching Resident Evil, and every time I saw a zombie, I shook and then after a few minutes or just a few moments, I felt my knees ache! It was like someone is squeezing them

So my question is, I have read about fear and I know that when we feel afraid their are certain changes in our body, but what makes us feel pain in knees while we are being scared of something?

I've heard about fear making a person go weak at the knees but not about knees paining as a consequence of fear. So maybe it's not that common? –  user4675 Oct 15 '13 at 3:27
    
yeah maybe, but the feeling I was having and still having is more like squeezing effect, like something is grabbing hold of my knees tightly.. –  Afzaal Ahmad Zeeshan Oct 15 '13 at 3:47
    
Blood flow increases because of adrenaline. This may make you feel weak after a while. But you seem to be suffering from a weird syndrome :P –  WYSIWYG Oct 15 '13 at 7:14
