this maybe a stupid ?? but if you aspirated and all was ok then the pin moved while you were inj, because i inject slowly about a 1/2ml a minute of any oil based... my ?? is if you accidently by moving the pin around got in a vein would you feel symptoms right away like say in a minute or so?? or would it take a while?? also what type of symptoms would you feel???that is why i inject so slow in case something is wrong, am i stupid for thinking this way?? thanks
