My arms and face tingle when i get an adrenaline rush, why?

Every time i get an extreme adrenaline rush, like when i am about to fight someone in MMA or do something extreme that i'm a little nervous about. Its the kind of feeling you get when there is no circulation in my limbs which i know only means the nerves are freaking out because there not gettin enough oxygen. I feel that if i were ever in a spontaneous situation where i would need to act like a self defense situation or what have you that this would really inhibit my ability to act. What is going wrong, and if this is normal what can i do to train my body to use adrenaline more proactively?
