how do you know if you hit a vein or nerve?

[Jburn]

it sounds like u didnt hit a nerve but maybe a vein. If you hit a nerve you would know it, you wouldnt even have been able to push it in a little bit more. if you hit a nerve you will ****ing want to cry instantly. it sounds like you may have gone through a vein if you felt a pulse but if you dont see bruising or if blood didnt come out then it may have just been a random occurence. unless you see extreme bruising or ****ing intense pain then no harm done. you can hit a nerve or vein and it wont really do any damage unless your using like a 18 ga needle bc that shit would be huge.

after i pulled out i did bleeed but not much i would compare the bleeding to the one you get after bursing a pimple (i know wierd example).
But i dont find it logic that my pulse was because of a vein because even tought veins do have some pulse its just on that spot like when you touch the artey on you neck, but my pulse was like a whole area, id even beleave it was the whole frontal muscle which pulsed so make sense it wasa nerve also when i tryed to move my arm like in a circle form y could feel like a wierd movement in something that felt like fibres or something which was stretching.
By the way if hiting a vein has that feeling why woud people bother in pulling the plunger(taking ou blood and reinjecting it can cause health problems, dont remember what was it called but ive heard it since child) if the could just weight to feel tht, is it rare to have pulses or what?
