Why do my legs feel weird? More info inside?

I'm afraid of heights and whenever I go near the edge of something I get this funny feeling in my legs like a rush of something for a couple of seconds. It also happens when I see things like open wounds or anything like that

You are experiencing an adrenalin rush, don`t worry this is a normal reaction to thing you fear.

I do the same thing too and my legs even get wobbly when i am up high or someone is going fast in the car with me in it.One time i hitchhiked in wash state and got into a van and in the back of the van was a shovel' rope ' blood on the shovel and i seen Starrs i was so scared; so soon as he stopped i jumped out' but crap i could not even walk as my body and legs were trembling so badly.Come to find out he was Gary Ridgeway green river killer' who killed like 60 or more girls and women.Even if i see a fight it makes me go crazy and get ill and i hate it .I think it's because there is nothing i usually can do ..humm who knows..lol

i get that.. it rushes to my head too. i think it's just an adrenaline rush. don't worry about it :)
