mate u kno if you hit an artery the pain is emmense u couldny physically push any more than a drop in, the pain is so unbearable, your hand would sewll so much u couldnt close it and it would go bright red all over and itch like fuck. believe me if u ever hit an artery u will know instantly there is nothing like it. and all taht after a tiny drop/ the closer to your extremitys the worse. u just missed ina sensitive area with not much fatty tissur too absorb it. Any1 who has done this in wrist/hand chime in and tell me if ive missed anything. an artery shot is scary and painful and dangerous. and your heart would beat like fucj and you'd go white. they r not meant too be hit and boy u would know if u hit it trust me.
