I hear I should "pull back" the needle once it is injected to see if blood comes up into, meaning I am in a blood vessle and should not inject. I have never done this. If blood does come back in the needle, do I need to find another location, or just pull it up a quarter inch? Also, if I did not hit a vessle and pull it up, what will come up in the needle? Some sort of bodily fluid ?
