moush when the muscle twicthes that doesnt nesseserely mean you hit a nerve. When I inject, my muscle twitches sometimes also. "i got dizzy, lightheaded and almost passed out" Those are signs of injecting in the vein. When you supposvly hit a nerve, did you still keep on going and inject the stuff? I am curious if you did or not, coz like I said, "dizzy, lightheaded and almost passed out" are defenitely sings of injecting in the vein, and not really signs of hitting a nerve. Well no doubt you can still feel dizzy, lightheaded etc etc when you hit a nerve, but I wouldnt really call them main signs of hitting a nerve as the main sign of hitting a nerve would be the pain. Peace out
